title: Save R output to a different directory
body: <p>I am running some R code on a Windows computer using RStudio and my code generates Excel files and netCDF files periodically (dozens of them eventually). I don't want them to clutter my working directory. Is there a way to save the files to a directory called "Output" (ex:  C:/.../original file path/Output) in the parent directory? I would like a way to change my current working directory to a different directory. I understand there is getwd() and setwd() but how do I set the path to the output directory without typing out the entire windows path (for example: setwd(current source file path for windows or Mac/output). My collaborator uses a Mac and he would have his output stored there as well.</p>
