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
