R help - Jul 2007 - Subscript out of bounds when using datadist() from Design library

I am running R version 2.4.1 on Windows XP.  I have a question regarding the
datadist() function from the Design library.  I have a data.frame (call it
my.data) with 4 columns.  When I submit the code

datadist(data=my.data)

I get the following error message:

Error in X[[1]] : subscript out of bounds

I suspect there may be something wrong with my data.frame (I'm certain there
is nothing wrong with datadist()), but I don't know what.  Has anyone
experienced the mistake I seem to be making?

Regards,

You can just use
dd <- datadist(my.data); options(datadist='dd')

If that doesn't fix it, generate a test dataset that fails or do 
save(..., compress=TRUE) and send me your dataset so I can debug.

  If I follow the help page for datadist(), I think you want the following:

datadist(my.data)

  Note the following in the description of the data argument:

"Unless the first argument is a fit object, data must be an integer."

  A data frame is not a fit object, so I think that was the reason it
did not work for you.
