The working directory is > getwd() [1] "C:/Documents and Settings/Val/My Documents"
The data file(Rossi.dat) and the script(Rossi.R) are in "C:/Documents and Settings/Val/My Documents/R_data/prd" How should I write to read the file? source(???) # what should be included here? Rossi <- read.table('Rossi.dat',header=T) > I still got the same error message. Error in file(file, "r") : cannot open the connection In addition: Warning message: In file(file, "r") : cannot open file 'Rossi': No such file or directory Thanks Val On Wed, Oct 28, 2009 at 10:32 AM, David Winsemius <dwinsem...@comcast.net>wrote: > > On Oct 28, 2009, at 10:04 AM, Val wrote: > > Hi User's, >> >> This might be a simple question but it is giving me a hard time as I am a >> new user. >> I installed R version 2.9.2 (2009-08-24) >> >> 1.
