Hi,
that should do:
mat <- rbind(c(20,200,100,50,100,30),
c(100,200,100,50,100,30),
c(50,200,100,50,100,30))
rownames(mat) <- c("2016-11","2016-12","2017-01")
t(apply(mat,1,cumsum))
Best,
Christian

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
