Hello, 1) I would like to add three function to the file colorstuff.R in the grDevices package. These functions would be: red.colors <- function(n, start = 0.3, end = 0.9, gamma = 2.2) green.colors <- function(n, start = 0.3, end = 0.9, gamma = 2.2) blue.colors <- function(n, start = 0.3, end = 0.9, gamma = 2.2) As you can see, these are simply analogs of the function grey.colors, and would be useful for image processing code done in R. This would be a simple change, with little impact on existing code. Documentation for the three new functions would be added to gray.colors.Rd. I could make the necessary changes, and would volunteer to make the changes, but don't have SVN access. 2) Can someone explain the origin of the naming system for these functions? I would have thought function names such as palette.terrain, palette.gray, palette.heat, etc. would be more obvious to users. A change such as this would obviously be more intrusive, but could be easily accomplished over a transition period. The old function names could be depreciated, while still pointing to the correct code.
