R: read.csv adding sub-script “X” in header

Question

I have a data frame that has headers as this

Name  0x1  1x2

read.csv changes the header to be

Name X0x1 X1x2

Answer 1

I had the same issue on my Mac. There was a X... at the beginning of the first variable. The problem was that the CSV file was actually a CSV UTF-8 (Comma delimited) file. Saving the file as a CSV (Comma separated values) solved it.
