drop columns whose rows are all 0
...ome of them are always 0 (each
row). I would like to make a subset containing only the columns which
values are not all 0, but I don't know how to do it.
I tried:
for(cut_column in 1:40) {
if(sum(dataset[,cut_column])!=0) {
columns_useful<-c(columns_useful,dataset[cut_column])
}
}
sorted_dataset<-subset(dataset, select=columns_useful)
But it doesn't work.
Thank you
