By default when I clicked file --> save as ---> the window asks file
name and shows save as type --> R files(*.R) file type. In my case I was
typing only the file name " Ross" without the extension assuming that the
window will append the extension since it asked me R files(*.R). I thought
it is just like the other windows program like Word or Excel. Now I have
to type the full file name Ross.R.
The script file name is Ross.R
*
*Rossi <- read.table(paste("C:/Documents and Settings/Val/My
Documents/R_data/prd", "Rossi.dat", sep="/"), header=T)*
the console output is
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") :
cannot open file 'C:/Documents and Settings/Val/My
Documents/R_data/prd/Rossi.dat': No such file or directory
