You should read some of the free tutorials about R. Also use dput() to send
your data and plain text (no html) emails.
> dput(mtx)
structure(c(20L, 100L, 50L, 200L, 200L, 200L, 100L, 100L, 100L,
50L, 50L, 50L, 100L, 100L, 100L, 30L, 30L, 30L), .Dim = c(3L,
6L), .Dimnames = list(c("2016-11", "2016-12", "2017-01"), NULL))
> t(apply(mtx, 1, cumsum))
[,1] [,2] [,3] [,4] [,5] [,6]
2016-11 20 220 320 370 470 500
2016-12 100 300 400 450 550 580
2017-01 50 250 350 400 500 530
Use ?dput, ?t, ?apply, and ?cumsum to read the manual pages for these functions.

Subject: [R] summing up a matrix
Hello together,
is it possible, to summing up a matrix?
I have the following matrix at the moment:
[,1] [,2] [,3] [,4]
[,5] [,6]
2016-11 20 200 100 50 100
30
2016-12 100 200 100 50 100
30
2017-01 50 200 100 50 100
30
Now I want to summing up the matrix in a new matrix.
The result should look like the following:
[,1] [,2] [,3] [,4]
[,5] [,6]
2016-11 20 220 320 370 470
500
2016-12 100 300 400 450 550
580
2017-01 50 250 350 400 500
530
Is it possible, to create that?
Thanks for your help.
Best regards.
Mat
