Val, please take it slow, you are missing basic stuff here.

*   Yes I looked at it and it only shows type.  To check I downloaded
another script with   R extension "test.R" and the type column shows the
exact extension(i.e., test.R).

      *  Rossi <- read.table( file.choose(),header=T)

*Why I  can not open with this command?*

Rossi <- read.table("C:/Documents and Settings/Val/My
Documents/R_data/prd/Rossi.dat",header=T)

*David,
*You suggested to use ,

Rossi <- read.table(paste("C:/Documents and Settings/Val/My
Documents/R_data/prd", "Rossi.dat", sep="/"), header=T)

This is not working as well  I got the same error message.

Any help is highly appreciated
