I'm trying to use data for visualization later, but I can't seem to get past this part. I entered data into an excel file and save it as a .csv to read in the code. But when I try to select specific columns from my data set, I get this error. I thought setting my header = TRUE would help identify my column names, but I guess it doesn't? I'm just selecting the first two columns for the sake of testing if the select function will work, but I will end up trying to select a few other columns to visualize them.
I also tried renaming the column "Rank" to "rank" just to see what would happen, but I got another error and don't really know what it means.
Rank = structure(list(Rank = c(1L, 2L, 3L, 4L, 5L, 1L, 2L, 3L, ...
Thank you for your time!
