projectDirs
projectDirs is an RStudio Addin that allows you to create a configurable set of folders (directories) in an RStudio project. Additionally, it provides a way to move an existing set of files into these folders based on either their extensions or using regular expressions on the file names.
Installation
You can install the released version of projectDirs from GitHub:
# install.packages("devtools")
devtools::install_github("joranE/projectDirs")Usage
It is often desirable to use a consistent directory structure for your
RStudio projects. After installing projectDirs, a command “Create
Project Directories” will be added to the Addins drop-down menu in
RStudio. The default set of folders created are “r”, “data” and
“figures”, but this can be configured by setting the
projdirs.folders option in your .Rprofile:
# Put this in your .Rprofile
options(projdirs.folders = c("r","input","output","plots","cache"))The above example will create folders with those names at the top level of the current project.
Often we create an RStudio project around a pre-existing set of files
that need to be moved into the resulting directory structure.
projectDirs also provides the Addin command “Place Files By Extension”
that will move files at the top level of the project into folders based
on their file extension. This is configurable via a named list in
options().
For example, setting:
# Put this in your .Rprofile
options(projdirs.file_ext_map = list(r = c("r","R"),data = c("csv","tsv","txt")))will move files with the extensions “r” and “R” into the folder “r” and files with the extensions “csv”, “tsv” and “txt” into the folder “data”. If folders by these do not exist, no action is taken for that rule.
Finally, we can also move files into directories based on regular expressions on the entire file names with the Addin command “Place Files By Regex”. For example, the above mapping could also be done via:
# Put this in your .Rprofile
options(projdirs.file_regex = list(r = "r$|R$",data = "csv$|tsv$|txt$"))Once again, if no folder “r” or “data” exists that rule is skipped.
