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
