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!

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()
