R help - Apr 2014 - How to use rainbow function without the gamma argument

Hi all,
I am using an old code (probably written for R 2.5) and it stops when
calling rainbow() with gamma argument. I saw that gamma argument is not
present in newer version of R rainbow function. How can I translate this
line of code:

rainbow(100, s = 1.0, v = 0.75, start = 0.0, end = 0.75, gamma = 1.5)

?

It fails with:

Error in rainbow(100, s = 1, v = 0.75, start = 0, end = 0.75, gamma = 1.5)
:
  unused argument (gamma = 1.5)
Calls: nmfconsensus ... matrix.abs.plot -> image -> image.default ->
rainbow
Execution halted

Thanks

Have you looked at ?rainbow ?
Is there a reason why you don't simply leave the gamma parameter away?

Try:
pie(rep(1,100), col=rainbow(100, s = 1.0, v = 0.75, start = 0.0, end = 0.75))

Cheers,
B.
