If the result of the 'table' is a different length each time, then you will have to consider the use of a list. If it is the same length, then something like this should work
results <- matrix(ncol=50, nr=10) for (i in 1:50) results[,i] <- your computation for table On Wed, Sep 9, 2009 at 12:40 PM, drlucyasher<las...@rvc.ac.uk> wrote: > > Apologies for what might seem like an simple question. > > I have written a model which gives me a frequency distribution for a > particular score within a set.
