Hello!

I'm not a very experienced programmer so I'm sure there's something I need to do that I am simply unaware of...but when I run my cv.rmd, I get the following error message from line 24-28:

Error in if (!after) c(values, x) else if (after >= lengx) c(x, values) else c(x[1L:after], :
missing value where TRUE/FALSE needed"

Inititally I thought that maybe my .csv files weren't reading in properly, but I checked by just adding them to a dataframe, and they are reading in fine...does anyone have a good idea for me? Thank you in advance!

PS: I've of course tried adding show_col_types to the function in line 24, but that only got me an error message saying the function can't use that command..
