Hi Val,

Windows does not display extensions by default. Check the 'Type'
column; it should read 'R file'.

Keep in mind what you are dealing with; Rossi.R is a script, so you
cannot open it with read.table. You have to use source() for that.
Moreover, use the extension, as well (Rossi.R, not Rossi)

Cheers!
