Hi, I was trying to get an image/pdf of a sequence of colors in the order given. For example: myCols <- c('#0000BF','#0000BF','#0000FF','#0000FF','#0000BF','#0000FF') I'd like to make a strip of colors as they appear in the order above and save it as a pdf file. Is there a function in the base package (or some other package) to do this? thanks! [[alternative HTML version deleted]]

Hi, Perhaps the easiest way is with grid.raster, library(grid) pdf("colorstrip.pdf", height=1, width=10) grid.raster( t(myCols), width=unit(1,"npc"), height=unit(1,"npc"), interpolate=FALSE) dev.off() HTH, baptiste On 20 October 2011 03:32, Brian Smith <bsmith030465 at gmail.com> wrote:> Hi, > > I was trying to get an image/pdf of a sequence of colors in the order given. > For example: > > myCols <- c('#0000BF','#0000BF','#0000FF','#0000FF','#0000BF','#0000FF') > > > I'd like to make a strip of colors as they appear in the order above and > save it as a pdf file.
