Hello everyone,
I have a problem using a for-loop to go through a matrix. I want to remove all
rows with a sum of 0.
What I do is basically:
for(i in 1:length(data))
{
if(sum(add(data[i,]) == 0)
{
data <- data[-i,]
}
}
I get a error message: "Error in `[.data.frame`(data, i) : undefined columns
selected", because the length is reduced when removing in the if-clause.
How do I make this?
Best wishes,
Markus
