...ate non-parametric probabilities using the np package and having some difficulties. OS is Windows, R version 2.11.1 Here is what I've done so far. library(np) veg <- data.frame(factor(Physiogomy), meanAnnualDepthAve, TP) attach(veg) : for clarification dim(veg) returns 1292 3 fy.x <- npcdens(veg$factor.Physiogomy ~ veg$meanAnnualDepthAve, nmulti=1) # this works, but I haven't found any information explaining what the nmulti=1 term is doing? Does this set the number of levels in the factor? My data actually has 8 types, can I develop this to treat each one in a single function ?...

...be performed on npreg outputs. * added a vignette and faq. * summary on npconmode now properly retrieves names from bandwidth objects. * fixed the 6th and 8th order epanechnikov kernels. * fixed some quietness issues. * npplot now returns data upon request for conditional densities. * npreg and npcdens now take the appropriate limits in some pathological cases. We are grateful to John Fox, Achim Zeilies, Roger Koenker, and numerous users for their valuable feedback which resulted in an improved version of the package. -- Jeffrey Racine & Tristen Hayfield. -- Professor J.
