I am refreshing my R loops skills. How can I write a loop for the below codes. The column indices are 10:14.
length(data[which(data$subject == "notcoded"),"subject"])/length(data[,"subject"])
here:
for (i in 10:14){
length(data[which(data[i] == "notcoded")[[i]]])/length(data[i])
}
I kept getting errors about undefined column. I have tried multiple ways to use and []

You are subsetting your data but not specifying a column. Usedata[,i]
