Our data scientists have excellent knowledge and understanding of the R programming language and the free software environment to make sense of collected data through statistical computing and the use of graphical techniques. This article contains information about some of the factors we consider in our R studio software data analysis services.
Factors we Consider When Analyzing Data Using R software
Understanding the R language is essential in data mining and the development of statistical analysis. The statistical software helps in creating effective analysis solutions and processes. R has continued to gain popularity over the past three years; being ranked at the 8th position in August 2020, representing an improvement from the 20th position in 2019 the same month. Some of the factors we consider during R studio software data analysis include:
1. Data types available for statistical analysis
It is fundamental to understand the data types and how to handle them to effectively use the R studio software. The basic data types in R analytics include numeric, integers, characters, logic, and complex. We utilize the functions provided in R and the programming language to make sense of the data.
2. Data structures and compatibility with R software for statistical computing
To correctly analyze data using R, we must first understand its storage structures such as lists, vectors, matrices, factors, and data frames. Structures such as vectors and matrices require that members of the dataset be of the same type while others like the lists and frames allow the inclusion of different types of data.
Whichever structure that the client presents, they can rest assured of the best output after ordering our R studio software data analysis services. Data structures are the objects for manipulation during R statistical analysis. We create interactive dashboards and reporting tools to display each input and output appropriately.
3. Directory commands
The integrated development environment in R studio software entails the creation of working directory commands. The R studio software allows one to run the user-created packages in a friendlier environment. After launching the software, we specify the working directory for R to use in reading and saving files.
The R packages for creating files, typing commands, and viewing their histories and plots are essential to running R in the software environment. With a default working directory, all the commands are correctly used to bring out the desired output.
4. Data frames
Data frames generalize matrices in which columns vary in modes and are essential when using R programming and modeling functions. For any given column in a data frame, we ensure all the elements are in the same mode. We correctly input character string vectors in datasets to aid in effective analysis. In-built data frames in R packages must also be handled correctly using the right command to yield reliable outcomes.
5. Functions
Every member of our team is conversant with all the relevant functions and the R programming language. Using the right functions is essential to running the correct command for the desired output. We, therefore, apply a function to a data frame column depending on the characters contained in such a column and the type of action desired.
The mixing and matching of elements in a dataset, operations with vectors of text strings, merging data frames, working with dates in R base, writing, and other code functions for graphing and data management are appropriately used in our analytic processes. All plotting and conversion functions are correctly used in our R studio software data analysis services to display desired outputs.
6. Data wrangling and cleaning
After precise data collection, it is essential to clean, untidy, manipulate, and merge datasets to desired formats that are compatible with R studio software for effective analysis. We offer the best R data analysis help to clients owing to the use of essential techniques for cleaning datasets and formatting variables to enhance effectiveness.
Where necessary, we transform continuous variables into categorical ones, add new, append, merge, split, stack, or unstack data frames, and fix missing values for an effective analysis process.
In any data science project, the R software environment provides useful resources for manipulating and cleaning data before analysis. We also enter the data into R in a useful format for modeling and visualization. After wrangling and cleaning for tidy datasets, modeling, visualization, and transformation processes are easier during analysis.
7. Exploratory data analysis (EDA) using R language
When conducting EDA using R, our experts create frequencies and proportions tables, cross-tabulate categorical variables, and conduct descriptive statistics for continuous variables.
The EDA makes it easier to visualize data and derive insights from the analysis process that can be communicated to relevant target audiences. We follow all the EDA steps appropriate for the specific dataset in our R studio software data analysis services to ensure clients receive the best and most reliable outputs.
8. Data visualization
Excellent R software developers from our company create collections of functions and datasets to increase the power to visualize data during analysis. We are capable of using the various systems provided by R for creating graphs and charts, including the ggplot2. We customize graph attributes such as axes, texts, titles, or legends for both categorical and continuous variables.
In addition, our R data analysis experts can effectively use graphical techniques to describe the relationship between variables, depending on the nature of research questions and objectives. R analytics can summarize data using both graphics and numeric values, hence, we choose how to visualize depending on the characteristics of the datasets and the study objectives.
9. Mean comparison test in R
We use the relevant functions when comparing the means for two samples and the confidence interval with regard to the mean differences from the independent samples. Our R data analysis experts also run classical statistical tests; including the t-test for the independent samples. Our prowess in data science, statistical models, and the R software environment makes us the ideal solution for anyone wishing to purchase the services of an R data analyst.
We carefully calculate the means confidence interval for both independent and paired samples as well as comparing frequencies. In addition, the confidence interval for the difference in proportions, risk, and odds ratios are calculated using the appropriate commands and displayed in the R interactive dashboards as outputs.
Given big data for analysis that require the calculation of mean comparison tests using R, we understand the commands to run for outputs on a one-sample t-test, paired sample t-test, independent samples t-test, or one-way analysis of variance(ANOVA).
10. Tests of associations in R
Although measures of associations can be used in various fields of research, we mostly apply them in epidemiology and psychology projects that seek to establish and quantify the relationship between exposure to certain factors and specific diseases or behaviors. Both correlation and regression analyses can be used to determine the measure of association between variables.
The most common measures or tests of association we use in our R studio software data analysis services include the Chi-square, Pearson's correlation coefficient, and Spearman's Rank-order Correlation. We choose the type of test to use in measuring associations depending on the characteristics of the data available for the variables of interest.
11. Use of predictive regression models in data science
Predictive regression models are used in data science to forecast future outcomes in research. Both linear and nonlinear modeling is important in R programming. Linear regression, being one of the basic algorithms used in data science is effective in predictive analysis of the association between variables in a study. We also use the multiple linear regression model, a statistical technique to establish the presence of a linear association between multiple independent variables and a dependent variable.
For industries such as the banking and retail sectors, we use nonlinear modeling to sort and analyze data to draw conclusions and provide a prediction for future trends depending on user activities and behaviors.
The binary and ordinal logistic regression models can also be used appropriately depending on the characteristics of the dataset. No matter the field or the size of dataset one may have, our R studio software data analysis services can handle all customer needs on a 24/7 basis.
