What is producing the error "Argument 2 must have names"

rstudio

#1

Hello,

This below is 1) the result of running the code,
Error in cbind_all(x) : Argument 2 must have names
Called from: cbind_all(x)
Browse[1]> > print(class(dataList)) [1] "data.frame" > print(class(new_filenames)) [1] "data.frame"

  1. and the reprex of the code I am writing now.
    How can I attach the files? Should I copy and paste them?

thanks
