Hi Nick, Your code is not exactly "commented, minimal, self-contained, reproducible" and contains a number of inconsistencies (Data has three elements, your loop expects six). Try something like
Data <- c("July", "August", "September") ... for( x in Data ) { currentData <- read.csv( paste( x, ".csv", sep = "" ), header = TRUE ) ... } to get your loop going.
