r - Permission Denied Error when downloading a file -

i trying download excel zip file r project folder have started. i'm new r i'm little puzzled @ error message i'm receiving.

the file excel file , first created variable file:

excel2file="http://op.nsf.data/datafiles/housing2013excel.zip"

then used coding:

download.file(excel2file, destfile= "~/home/documents/data")

i receive error message:

error in download.file(excel2file, destfile = "~/home/documents/data") : cannot open destfile '~/home/documents/data', reason 'permission denied'

i tried looking @ other examples of permission denied , think may destination file not sure why or steps problem shoot it.

destfile should filename, not directory. example:

download.file(excel2file, destfile= "~/home/documents/data/housing2013excel.zip")

also, url doesn't seem valid, that's different (non-r) problem.

r
