2. Map your values to a range of integers that you can use as indices
How can i use colour gradient according to y axis if the y values not
increasing gradualy

Another trick if Bill is correct is to sort the data first, by whatever
variable the color is intended to represent.

Points later in the input vectors may be obscuring earlier
points. If that is the problem then use pch="." or cex=.2
(or some other small number) to make the plot symbols
smaller so they don't overlap as much. Sometimes using
transparency helps also - try using adjustcolor(Color(n), alpha.f=0.5)

Please tell us what you're trying to accomplish. "not working" is rather vague.
Without a reproducible example that includes some sample data (fake is
fine), the code you used, and some cle
sir i done this plot(1:33292, 1:33292,col=Color(33292)) command then it gives
the coloured line but again it is not working in my data why?

Try this
plot(1:33292, 1:33292,col=Color(33292))
and then decide again whether or not it is working.

1. Don't use Nabble for the r-help mailing list.
2. Read the posting guide, and read http://adv-r.had.co.nz/Reproducibility.html
3. The following code works for me. Your error is not due to requesting too
many colours...
n <- 10
x <- rnorm(n)
y <- rnorm(n)
myPalette <- colorRampPalette(c("r
Your example is not reproducible. You pass 33292 colors to plot, but never
specify how to use them so only the first color (red) is used. If it worked
with a smaller number of colors, you were using something other than the
default plot function. If it works with a smaller number of colors, but
9 matches
