Hi R users, Is there a simple function that can add a folder into current R search path? For example, suppose my current work directory is "D:\work", but my input files are stored in folder "C:\inFiles\", I know I can change work directory or add "C:\inFiles\" before files name when I scan them, but I don't want to do that. I want to find a function that can simply add "C:\inFiles\" into R's search path, so that we I scan a file R will go to all the search paths to find it. In matlab, path(path,"C:\inFiles") will do this job, I'm just wondering if there is a similar function in R can do this job. Thanks, zhiliang [[alternative HTML version deleted]]
Yes, it is.
The original is here

However, it requires some modifications.
Here they are. Sorry, I can test it only in Windows.
search.source <- function(file, path=Sys.getenv("PATH"), ...)
{
for(p in strsplit(path,.Platform$path.sep)[[1]]) {
fp <- file.path(p, f)
if(file.exists(fp)) return(source(fp, ...))
}
stop("file ", sQuote(file), " not found")
}
Try also looking here.
