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

count the sum of groups as 2 for "mauro-francesco" or do they count as
