If you look at the code for that function you see this line: logi.curve <- function(independ, depend, mod = logi.mod, col.cur = "red", lwd.cur = 4) { Since it's the only occurence of "red" that's probably where "the money lies". You can either do a "hard hack" where you alter the value of the parameters to that inner function, ... or you can add a named parameter after the dots in the outer parameter list such as: function (independ, depend, logi.mod = 1, type = "dit", boxp = TRUE, rug = FALSE, ylabel = "Probability", ylabel2 = "Frequency", xlabel = "", mainlabel = "", las.h = 1, counts = FALSE, ..., col.cur = "red") ... and modify the inner function to read: logi.curve <- function(independ, depend, mod = logi.mod, col.cur = col.cur, lwd.cur = 4) { > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
