Thank you David, you're absolutely right. The critical point here is par settings of fields::image.plot not the axis(1,at=?...) as could be understood from the original partial question. I forgot to cc the list on my private communications with the OP. Future googlers, the same solution can be achieved with A<- matrix(1:50,nr=10) par(mar=c(5.1,2.1,4.1,4.1)) image(t(A),axes=F,col='transparent') axis(1,at=seq(0,1,l=ncol(A)),labels=LETTERS[1:ncol(A)]) require(fields) image.plot(t(A),add=T,legend.mar=3.1) Cheers > >> >> >> ----- Original Message ----- >> From: ilai <ke...@math.montana.edu> >> To: David Lyon <david_ly...@yahoo.com> >> Cc: "r-help@r-project.org" <r-help@r-project.org> >> Sent: Tuesday, April 3, 2012 10:43 PM >> Subject: Re: [R] image.plot adding x-axis labels.
