Dear All,
I hope you don't mind helping me with this small issue. I haven't been using
R in years and I'm trying to fill in a matrix
with the output of a function (I'm probably using the Matlab logic here and
it's not working).
Here is my code:
for (i in 1:length(input)){
out[i,1:3] <- MyFunction(input[i,1],input[i,2], input[i,3])
out[i,4:6] <- MyFunction(input[i,5],input[i,7], input[i,6])
out[i,7:9] <- MyFunction(input[i,8],input[i,10], input[i,9])
}
'input' is a matrix
> dim(input)
[1] 46 10
and each raw corresponds to a different subject.
The error I get here is
/Error in out[i, 1:3] <- get.vaTer(input[i, 2], input[i, 4], input[i, 3], :
object 'out' not found/
So I wonder, what's wrong in the assignment to the variable out?
Should I define the variable before the loop?
Thanks for your help
Best
Ale
