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

Using the quote="" option will also prepend an X. for each column of your data.frame. If you can, try to remove that from your read.csv options, else add the check.names=F option which will override that behavior.
