Hi Christian,
You could use the ggplot2 package (http://had.co.nz/ggplot2) which

qplot(Height, Volume, data=trees, size = Girth)
qplot(Height, Volume, data=trees, size = Girth, colour=Height)
You can find more details on the website about how to

Here is a function that will generate a color sequence for an input
vector, You can specify the colors to use, the range and the number
of color steps:
# specify the colors and the number of increments you want for a specified
# range. It will return the colors for the input vector
