See also file.path() and create.dir(). You can use them with getwd() and setwd() to specify and/or create subdirectories, relative to your current working directory. Handy because they allow you to create paths and directories with names derived within functions.
For example, I have used them to create output directories that reflect dates when successive data summaries were prepared. > #Current working directory is "c:\temp" > #Creates a subdirectory, "data," relative > #to current working directory > wd <- getwd() > sub <- file.path(wd,"data") > dir.create(sub) > #Changes working directory > setwd(sub) > getwd() [1] "C:/temp/data" > #Changes back > setwd(wd) > getwd() [1] "C:/temp" julien cuisinier wrote: > > > > > > Dear list, > > > > What I would like to achieve is to make this "PathUpload" relative to were > R is at the time I launch it using the R CMD BATCH command > > so I would end up with something like "PathUpload <- './uploads'" (as in > php in this example) > > > ________________________________________________________________ > > > [[alternative HTML version deleted]] > > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > > -- View this message in context: http://www.nabble.com/Relative-paths-in-R--tp24738390p24742361.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
