I am reading a txt file into R and trying to do take the log of the data. The txt file has columns of data with the first row having text headers and the rest numeric data.
data=read.delim( "data.txt", sep = "\t", row.names = 1)
I get the following error when I do this:
Error in Math.data.frame(data) :
non-numeric variable(s) in data frame: tumor1, tumor2, tumor3, tumor4, normal1, normal2, normal3
