[R] Dplyr question

[Richard O'Keefe]

Why do you want to use dplyr?
It's easy using base R.

original <- ...
a <- cbind(original[,-3], Location=colnames(original)[2])
colnames(a)[2] <- "Measurement"
b <- cbind(original[,-2], Location=colnames(original)[3])
colnames(b)[2] <- "Measurement"
result <- rbind(a, b)[,c(1,3,2)]
