So I’m having trouble working this out. I have multiple CSV files with the same two columns: Wavenumber and Intensity. The Wavenumber column for each file is the exact same, so I don’t really care about that one. Is there a way to extract the Intensity column from every CSV file and put them all into a data frame? I’ve found a few answers for using one CSV file, but nothing for multiple.

I’ve tried using list.files and lapply with fread, but that makes a list of data frames of the CSV files, which could work, but I eventually need to graph these against each other.
