Then you don't have a column named exactly "S.Sharif" in your object
"data".

What does str(data) and names(data) tell you about the columns in your
data set? If looking at these doesn't help you, post the output from
str(data) and names(data) and someone might be able to help.

You should always check that R has imported the data in the way you
expect; just because you think there is something in there called
S.Sharif doesn't mean R sees it that way.

You also seem to have included the R-Help email address twice in the To:
header of your email - once is sufficient.
