No. The OP's "variables" appear to be vectors. sum() sums columnwise
(vectorwise).
Something like
rowSums(cbind(var1,var2,var3,var4,var6), na.rm=TRUE)
appears to be what is wanted. But of course,Jin Choi appears to need
to do some homework -- e.g. by reading the Introduction to R online

Hello,
I have a matrix (class matrix) composed of GridCell (row and column).
The matrix value is the beta diversity index value between two grids.
Now I would like to get the average value of each GridCell.
Please kindly advise how to make the calculation.

Folks:
I think it worth noting that the solutions provided by Brian and
David, which look exactly the same when print()ed, are entirely
different beasts. Brian's gives a column of strings; David;s gives a
column of lists (a list of lists). str() will provide details.
Both solutions are "correct"
Not sure whether I understand your question fully but I guess paste() is your
