Simple color strip

Hi Duncan,

Yes, I'd like it without any gaps. There are likely to be at least a hundred
colors, so something that is not as 'tall' (ideally an inch?) and that would
be a mm or two for each color.

thanks!

 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?

 barplot(rep(1, 6), col=myCols, axes=FALSE)

 There are other options to barplot if you want the bars horizontal, without
 spacing, etc.

 Putting it in a pdf is simple:  just open the pdf() device before you draw,
 and close it afterwards.
