Hi, I was trying to draw an empirical distribution function with uniform confidence bands. So I tried to find a way to calculate values of the Kolmogorov-Smirnov Distribution but failed. I guess it must be hidden somewhere (since the ks-test is implemented), but I was unable to find it. Is there any way to do this? Thanks Leif Boysen

Hi, As will soon be very clear I'm an R novice. I'm trying to better understand the ks.test function in the stats package. When I look at the source code there are several calls to C functions (for example .C("pkstwo", is.integer(length(x[IND])), p=as.double(x[IND]), as.double(tol), PACKAGE = "stats)$P). I'm wondering if there is a way to view the source code for the underlying C functions? I googled a post which said to open ks.c to see the source code but I can't find that file anywhere on...

Greetings, I have two questions that I could not answer from the documentation. A - ecdf and confidence intervals : Is there a (simple) way to generate confidence intervals (95%) for a ecdf? B - cross-validation of rpart trees : a colleague is using S to generate decision tree and mentioned to me the use of cross-validation. Is this function enabled in R ? if so, how should one proceed to
