Hello, I try to compute means,sd,n from a variable y according to some
categoricals g1,g2... I wrote the following function:
gg <- list(...)
this works OK so far there is no empty cell in the crosstab, if there
is, the unlist statement just run over it and I do not know which cell
is missing, any attempt to label the columns in matrix bb then fail.
Can somebody suggest a method to retrive the list names from aa to label
the columns of the matrix bb?
Thanks for any help
