[R] Accessing scripts in a different directory on a Mac

[Tim Calkins]

consider something along the lines of:

>scriptdir <- '/path/to/scripts/"

>source(paste(scriptdir,'subscript.r',sep=''))


alternatively, you could try:

>workdir <- getwd()
>scriptdir <- '/path/to/scripts/"

>setwd(scriptdir)
>source('subscript.r')
>setwd(workdir)


cheers,
tim
