Frankly, this is great. I don’t really care if it base or tidy, I just need it
to work.
Thank you kindly!

Hi Shawn,
Here is a solution using base R (no dplyr). The only regex appears in the
statement to get the common prefixes.
colsPrefixes <- sub("_Planned$","",colnames(gross_test)[
grep("_Planned$",colnames(gross_test))])
f <- function(s) {
gross_test[,paste(s,"Diff",sep="_")] <<-
gross_test[,past
2 matches
