[R] Help for funnel plot

[Jim Lemon]

Hi,
There are a number of functions that will transform numeric values
into colors. One is color.scale in the plotrix package. This accepts a
vector of numeric values and linearly transforms them into one or more
ranges of colors. The resulting colors can then be passed to the
appropriate arguments in your plotting function.
