[R] problem with ad.test

[Bhismadev Chakrabarti]

dear experts,

i am a novice and  have been trying to use the anderson-darling test
on a simple text file with one column of data.
i have followed the example in the manual to read from a file into a vector(mm).
i am able to see the summary stats with
>summary(mm)
however, when i try to use the ad.test package, it keeps coming up
with the following error messages,
> ad.test(mm)
Error in "[.data.frame"(x, complete.cases(x)) :
        undefined columns selected
>
> ad.test(EQ)
Error in inherits(x, "factor") : object "EQ" not found

EQ is the name ( in the top row of the column, imported with
read.table( file, header=TRUE) of the column of the data.

i am really sorry if this is very basic, but i have not been able to
locate anything specific on how to avoid this error message in the
archives.

any help is highly appreciated,

bhisma
