Hi All,
I have the following problem (read the commented bit below):
a<-matrix(1:9,nrow=3)
a
[,1] [,2] [,3]
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
div<-1:3
apply(a,2,function(x)x/div) ##want to divide each column by div-
instead each row is divided##
[,1] [,2] [,3]
[1,] 1 4.0 7
[2,] 1 2.5 4
[3,] 1 2.0 3
apply(a,1,function(x)x/div) ##Changing Margin from 2 to 1 does
something completele weird## [,1] [,2] [,3]
[1,] 1.000000 2.000000 3
[2,] 2.000000 2.500000 3
[3,] 2.333333 2.666667 3
Any thoughts?
Thanks,
Sachin
