Yes. That is what I do with my own functions. It is MUCH simpler than writing a package, though not as functional (no help pages for example.) Make sure the workspace has only the functions you need, then save it. In your .Rprofile, you can put a line like attach("d:/R/MHP/MHPmisc/.RData") to add the workspace to the search path. This has the advantage that the functions don't show up when you type ls() -- but they do when you type ls(nn), where nn is the position of the added workspace on the search path. I use the following script, stored in file 00make.r in the same directory as the functions, to speed this up: #============================== ## Script 00make.r MHP ## This clears the current workspace, sources all the scripts ## found in the working directory, and then saves the ## workspace for use by later R sessions # Clear all existing objects in workspace: rm(list=ls()) # Make a list of all R source files in this directory: flist = list.files(path = ".", pattern = ".+\.r") # Remove from the list all files containing the string "00": # Such files should be used for temporary functions or # scripts like this one. flist2 = flist[-grep("00", flist)] # Source the files: for (i in 1:length(flist2)) { cat("Sourcing", flist2[i],"\n") source(flist2[i]) } # Remove temporary objects: rm(i, flist, flist2) # Save workspace: save.image() # Write message to user: cat("\nNOTE: The workspace has been saved with all functions.\n", " When exiting R, please do NOT save again.\n") ls() in #=============================== -- Mike Prager, NOAA, Beaufort, NC * Opinions expressed are personal and not represented otherwise. * Any use of tradenames does not constitute a NOAA endorsement. ______________________________________________ R-help@stat.math.ethz.ch 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. ______________________________________________ R-help@stat.math.ethz.ch 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.
