I'm making a contigency table with a dataset which looks like:
Class Size Member1 Members2 Members3 etc.
1 2 A B 0
2 3 C D A
3 3 B A D
4 3 D A B
I make the contigency table with the ftab() function
I already found that I can 'export' the table when I use the is.table()
However I would also want to inlcude which class is with which frequency.
So the result I would like to have:
size Var1 Var2 Var3 freq
2 A B 0 1
3 C D A 1
3 B A D 2
Is this possible?
Another question: I've got a dataset with about 40 collums and about 20000
rows. Whenever I try to make a contigency table with all my data I get the
Error in vector("integer", length) : vector size cannot be NA
In addition: Warning messages:
1: In pd * (as.integer(cat) - 1L) : NAs produced by integer overflow
2: In pd * nl : NAs produced by integer overflow
Could anyone help me with this?
