Hi!
The message means that R does not find the file.
Under windows (if you are using windows) you must escape the backslash with a
backslash \.
or give us an example how you provide the path to the file.
Or use:
file.choose()
or.
library(tkWidgets)
fileBrowser()
both functions will return the proper path to the file.
Sincerely
Eryk
