Check, what "cols" is. This warning may be obtained, if "cols"
is a character value. For example
cols <- "a"
paste("V", 1L:cols, sep = "")
Error in 1L:cols : NA/NaN argument
In addition: Warning message:
In paste("V", 1L:cols, sep = "") : NAs introduced by coercion
> DATA<-read.delim ("D:\\DATA\\GeneExpression.txt",header=FALSE)
What is the relationship of this to the command above?
If you include a reproducible example, you have a better chance
to get a useful answer.
