[R] Deleting colmuns with 0's and also writing multple csv files

[DarioAustralia]

Hi Anna,

A column with all 0s will have a column sum of zero. So do this :

dataset1[, which(colSums(dataSet1 > 0))]

If you have a list of data.frames you could do this

for(index in 1:10)
{
        write.csv(yourListOfTables[[index]], file = paste("Dataset", index,
".csv", sep = ""), row.names = FALSE)
}

- Dario.
