your data are difficult to read so I make my own
set.seed(111)
sender-sample(letters[1:5], 20, replace=T)
receiver-sample(letters[1:5], 20, replace=T)
xtabs(~sender+receiver)
receiver
sender a b c d e
a 1 1 3 1 0
b 0 1 0 1 1
c 1 3 2 2 0
d 0 1 0 0 1
e 0 0 0 1 0
Hi
thanks for data. Probably others can come with better solution
with
library(reshape)
you can put your data to better form
dat2.m-melt(dat2)
dat1.m-melt(dat1)
merge them
dat-merge(dat1.m, dat2.m, by=Species)
and finally compute required values
select one site
temp-dat[dat[,2]==Site3
