Obviously I have been trying to use the colnames() function!
However, when I try to subscript ie:
for(i in 1:20){ main=paste("Site:",colnames(i),sep="") }
this doesn't work! I thought that as.character(colnames(i)) or substitute(colnames(i)) might work, but to no avail...
Laura,
You should (re)read ?colnames. It takes a matrix as it's argument, not an integer as you have supplied.
I think you want:
for(i in 1:20){
main=paste("Site:",colnames(mat)[i],sep="")
}--sundar

Hi,
Just a quick query - if I'm creating a function to produce a number of histograms per page of output (one per column from a matrix), how can I pass the column name of the matrix into the title (or indeed to form part of the x-axis label)?
By extracting them using colnames()?
