[R] Colour gradient is not working.

[sreenath]

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))
