I have a command that reads in some data:x <- read.csv("Sales2007.dat", header=TRUE) Then I try to organize the data: sc <- split(x, list(x$Category, x$SubCategory), drop=TRUE) Then I want to iterate through the data. I was able to get the following to run on the R console: for(i in 1:length(sc)) { sum(sc[[i]]$Quantity) } But notiing is primted on the console. I find that: for(i in 1:100) { i } Also does't output anything? I am probably making a wrong assumption here. Why desn't the loop seem to output anyything? Thank you.
Entering an expression interactively behaves differently than entering one in the context of another statement or function.
