In a documentation example, I want to use some functions from the car package. However, that package requires survival, which also includes a ridge() function, for coxp...

This may be elementary, but I can't find an answer: How can I set up global options for some specific arguments to functions in a package which can be easily changed by the user? This question relates to the selection of colors used in functions in several packages (heplots, genridge), where I want to provide reasonable default values for plots, but allow users to change those defaults globally for all plots produced with my functions. One solution is to use palette() for the default, as in foo <- function(x, col=palette(), ...) {} but the standard palette is not approp...
