  • What statistical analysis can you do in R?

    R is a reliable programming language for Statistical Analysis.
    It has a wide range of statistical library support like T-test, linear regression, logistic regression, and time-series data analysis.
    R comes with very good data visualization features supporting potting and graphs using graphical packages like ggplot2.Jul 4, 2023.

  • One common use of R for business analytics is building custom data collection, clustering, and analytical models.
    Instead of opting for a pre-made approach, R data analysis allows companies to create statistics engines that can provide better, more relevant insights due to more precise data collection and storage.
  • R provides a wide range of functions for obtaining summary statistics.
    One method of obtaining descriptive statistics is to use the sapply( ) function with a specified summary statistic.
    Possible functions used in sapply include mean, sd, var, min, max, median, range, and quantile.
Random forests for survival analysis was done using maximally selected rank statistics with ranger (4) package.

How can R help students analyze data?

Unlike analyzing data using point-and click interfaces, analyzing data in R involves writing code, which can make statistical thinking and data analysis processes more visible and reproducible; thus, the use of R may offer students an additional representational tool to build their understanding.

How to make data available for computations in R?

In a first step, we make the data available for computations within R.
The data function searches for data objects of the specified name ("Forbes2000") in the package specified via the package argument and, if the search was successful, attaches the data object to the global environment:

  1. R> data("Forbes2000"
  2. package = "HSAUR") R> ls()

Using The R Programming Language to Estimate A Linear Regression Model

The R programming language also provides functions to estimate statistical models.
One of the most commonly used model types is linear regression. Using the lm and summary functions in R, we can estimateand evaluate these models.
The following R syntax uses the variable Sepal.Length as the dependent variable and the remaining variables in the datas.

What is R in statistics?

What is R.
R is a powerful open-source programming language and environment tailor-made for statistical analysis.
Developed by statisticians, R serves as a versatile platform for data manipulation, visualization, and modeling.
Its vast collection of packages empowers users to unravel complex data insights and drive informed decisions.

Why is R so popular?

New statistical methods are quickly available because the R community is vast and active.
The source code for each function is freely available and everybody can review it.
Using the R programming language is free! That’s a significant advantage to relatively expensive statistical tools, such as:

  1. SAS
  2. STATA
  3. SPSS
