Hi, (please Cc me) In xyplot (), type = "l" (or one that includes "l", *el*) is (generally) meaningful only when the 'x' variable is sorted. In practice, one either sorts the data frame before hand or writes a tiny panel function which sorts the supplied x and then calls the default panel.xyplot(). Trouble arises when there is a conditional variable as well as a

Hi, Excuse me for using this list as a proxy for "r-sig-linux"! Is there anything analogous to `basename $0` (more importantly, "$0") of bash in R? Of course, this only makes sense in either BATCH mode or source() or shebang scripts (e.g using littler or Rscript)? Thanks for being considerate ;) -- Prasenjit

OK, here is the issue: I have a graphcis device (say X11) which I can set as active by dev.set(n). Is there ANY way to identify/infer whether this X11 device was obtained from a lattice function (like xyplot, levelplot...) or a standard function (like plot, scatterplot,...). A related question is whether plot.new (or frame) was called to obtain this graphics device... Thanks. PK

Hello: [Kindly Cc when replying] The question in a nutshell is this: Is there a more robust alternative to Ecdf ()? The details: I've used Ecdf () _a lot_ over the past few years and I have learned to live with its warnings. But I am running short on time and patience now [*] Here is a reproducible example: > library (Hmisc) > x <- read.csv ( file =

Hi, I have two matrices, A (axd) and B (bxd). I want to get another matrix C (axb) such that, C[i,j] is the Euclidean distance between the ith row of A and jth row of B. In general, I can say that C[i,j] = some.function (A[i,], B[j,]). What is the best method for doing so? (assume a < b) I have been doing some exploration myself: Consider the following function: get.f, in which,

Hi, A. In a nutshell: The training error, obtained as "error (ret)", from the return value of a ksvm () call for a eps-svr model is (likely) being computed wrongly. "nu-svr" and "eps-bsvr" suffer from this as well. I am attaching three files: (1) ksvm.R from the the kernlab package, un-edited, (2) ksvm_eps-svr.txt: (for easier reading) containing only eps-svr
