R help - Apr 2011 - Package fgui returns error: Object of type closure is not subsettable

Hello All,

I have written three functions.

First: To input user specified SAS dataset and plot the boxplots of relevant
variables.
Second: Extract the number of hours, minutes etc. from a variable describing
a time-point using regular expressions.
             E.g. 'Per1, Day 2, 24 Hour' would be separated into three
columns, Per (value 1), Day (value 2) and Hour (value 24)
Third: Finding the summary statistics of the relevant variables from the
data input using the first function.

All the functions are working fine in R console. However, when I tried to
use the 'guiv' function from the 'fgui' package, the last two
functions are
returning the error: 'Object of type closure is not subsettable'. The
guiv
function just provides a GUI to enter the function arguments.

guiv works well with the first function but returns an error only with the
second and third functions. What could be the reason? Could it be because of
the use of regular expressions?

Thanks

Nikhil
