lordsutch / dropquizzes.R
Created November 14, 2012 15:41
Add a variable to a data frame giving a mean of a set of quiz grades, dropping n grades
## Note: we're assuming each grade should be weighted equally here.
dropmean <- function(x, drop=2) {
count <- length(x)-drop
round(sum(sort(x, decreasing=TRUE)[seq(1, count)], na.rm=T)/count, 2)
}

infiles <- list.files(pattern='^gradebook-quizzes-[0-9]+\\.csv$')
for(filename in infiles) {
