[R] Reshaping a data frame

[Matthew Pharr]

I am new to R. Having come from SPSS and SAS to this program, I know
that my problem is
reshaping from long to wide. How would I go about reshaping data frame
(A) so that
information for each record is contained on one row. I am aware of the
R reshape
function, but I am uncertain of how to instruct R to reshape the data
set because I
need to move var1 (var1 is a survey question) out wide while placing
the values of var2 (var2 is the answer to the survey question) under
the correct survey question. Thank you for any help provided.

*Data Frame (A)
