Can you please help on the issue?
I using the apply command on a matrix below the example:
Create a vector
x =c(5, 3, 2:4, NA, 7, 3, 9, 2, 1, 5)
create a matrix of 2 rows by 6 columns
b=matrix(x, 2,6)
print(b)
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 5 2 4 7 9 1
[2,] 3 3 NA 3 2 5
using the command apply
print(apply(b, 1, function(y) sort(y, na.last=F)))
the output is a matrix of 6 rows by 2 columns.
[,1] [,2]
[1,] 1 NA
[2,] 2 2
[3,] 4 3
[4,] 5 3
[5,] 7 3
[6,] 9 5
As you can see in the example I start with a matrix of (2 by 6) and the
output of apply is a mtraxi of (6 by 2).
This is very strange because I was expecting as output a matrix of the same
dim (2 by 6) of the input matrix. I can solve this issues using an if
statment on the dim of the matrix but if I am using a square matrix I am not
able to control if the result of the apply is correct.
Do anyone find a solution to this issue?
thanks
Marco
