For example, my version of R in Linux has this as my default working directory. ![]() You can do this with the getwd() command. Know Where You Are in RĪfter understanding what you are seeing when you open an R terminal (or Rstudio), the next step is to know where R‘s working directory is. A file browser is also there if the user wants it. The bottom right panel includes various things like a tab for plots the user may have created and what packages are currently installed. The upper right panel allow the user to see things like objects in the current R session (more on”objects” later). The bottom left panel is an R script window, in which you can run commands into R. The upper left panel is an R terminal, the base around which the Rstudio program operates. If you open Rstudio, you will see something like this. In fact, R is less a “program” and more a programming language. The first thing first-time users of R may notice is that R is not a “push button, receive analyses” interface. Install the base R programming language, then install Rstudio. 1įor first-time users, I strongly recommend getting a graphical user interface (GUI) front-end for R. Windows users will want to select “base” to install the latest version of R. Any person can download and install R and all its capabilities without needing to shell out hundreds or thousands of dollars. R is also useful because it is free, unlike Stata and SPSS. It can handle advanced computational models better than some canned software packages like Stata and SPSS and can permit advanced users to write their own functions. ![]() Statisticians and quantitative researchers are moving to R because of its flexibility. R is an open source programming language with origins in C and FORTRAN. I prefer to teach applied statistical analysis to students using the R programming language as a guide.
