[R] Colour gradient is not working.

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 not more, you may
have overloaded the plot device.

Subject: [R] Colour gradient is not working.

I have a table of 33291 rows. When i try to plot the graph with gradient
colour using "colorRampPalette" command but the out put graph is
colourless
or in black colour.But when i try the same command with small values it is
working why it so?

Color <- colorRampPalette(c("red","blue"))

plot(x,y,col=Color(33292))
