Build R packages
With the R plugin for PyCharm, you can build your own R packages. The plugin provides you with the dedicated project type and handy UI tools to build, check, and test your sources.
To create a project, do one of the following:
From the main menu, choose
On the Welcome screen, click Create New Project
In the New Project dialog, select R Package from the available project types.
Specify the following parameters:
Location: the project directory name. This name is used to create a package title and construct filenames for all sources in the package.
Python interpreter. Expand the Python interpreter area and click next to the Base interpreter field. In the file system, select the R executable file. A sample path to the R executable can be /usr/local/bin/R on macOS or C:\Program Files\R\R-3.6.1\bin\R.exe on Windows.
Chosen package manager: the primary tools for building R packages in the project. Expand More settings and select a package manager from the list: Packrat, Rcpp, RcppArmadillo, RcppEigen, or Devtools. If you leave this setting unchanged, the default package managed will be used.
