Hi
I want to do something which seems straightforward, but I couldn't find the
way to do this.
I have a matrix called m for example, and a vector of values (let's call ind
this vector) which are indices of lines I don't want to keep.
for example I have:
> m
v1 v2 v3
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
[4,] 10 11 12
> ind
[1] 2 4
I would like to obtain this:
> m2
v1 v2 v3
[1,] 1 4 7
[3,] 3 6 9
by saying something like
m2<-m[!=(ind),]
but this line does not work.
Any idea or suggestion highly welcome !
Florence.
