Dear Jarod,
How about this?
a<- read.table(text="NAME1??? NAME2??? RNA
mauro??? francesco??? E234
luca??? giuseppe??? E5578
luca??? franco??? E5569
maria??? luca??? E4556
maria??? mauro??? E4556
luisa??? mara??? E4755
mara??? luca??? E234
luigi??? veronica??? E234
mauro??? veronica??? E235
francesco mauro????? E236
mauro francesco? E234
luca?? giuseppe?
E5576",sep="",header=TRUE,stringsAsFactors=FALSE)
vec1<- as.character(interaction(a[,1:2],sep="_"))
cbind(freq=sapply(split(a,vec1),function(x) nrow(unique(x))))
#??????????????? freq
#francesco_mauro??? 1
#luca_franco??????? 1
#luca_giuseppe????? 2
#luigi_veronica???? 1
#luisa_mara???????? 1
#mara_luca????????? 1
#maria_luca???????? 1
#maria_mauro??????? 1
#mauro_francesco??? 1

>I have another doubt.? If you have "francesco- mauro" (francesco
in 1st
column and mauro in 2nd column) and the RNA category is say E238.? Would you
count the sum of groups as 2 for "mauro-francesco" or do they count as
separate?>
