Non-numeric-alike variable(s) in data frame

Hi guys!

Does anyone know how to remove the header below because it keeps coming up with Error in Math.data.frame(Microarray.MSCs): non-numeric-alike variable(s) in data frame: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

Also, does anyone know what the R codes would be to perform microarray analysis in R.
I’m following this www.semel.ucla.edu/sites/default/files/coppola-lab/CoppolaExampleCode.pdf workflow.
