Save R output to a different directory

Question

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.

Answer 1

You can specify an argument in your write.csv function and other similar write functions which specifies your path.

#Output path
OutPath<- "C:/blah/blahblah/op/"

#Table to dump as output
OutTbl <- iris 

write.csv(OutTbl, file = OutPath)

Answer 2

You have a file argument in your write* function. If your Output directory is in your working directory, it works like this:

write.xlsx(df, file = "Output/table.xlsx")
write.csv(df, file = "Output/table.csv")
