Crash report: projection pursuit & predict
Folks, The projection pursuit regression function in the base R seems to crash when the optimization level is set to zero, i.e. the initial ridge terms are accepted without refitting. I encountered this problem in an out-of-sample prediction exercise using predict. But further investigation suggests the issue is with the ppr fit and predict just sppeds up the crash. The other optlevels seem to be

type conversion with apply or not
Folks, i thought it should be straightforward but after a few hours poking around, I decided it's best to post my question on this list. I have a data frame consisting of a (large) number of date columns, which are read in from a csv file as character string. I want to convert them to Date type. Following is an example, where the first column is of integer type, while the rest are type

source files in temp environment
Hi all, I often keep code in separate files for organizational purposes, and source() that code from higher level scripts. One problem is that those sourced files often create temporary variables that I don't want to keep around. I could clean up after myself with lots of rm()'s, but that's a pain, and is messy. I'm wondering if one solution might be to source the code in a

Missing functions in package e1071(Win*)
Hi! After unziping the CRAN file on my Win95 library directory, I start R and type >library(e1071) After that, help commands of the e1071 functions work (i.e., help(read.pnm), BUT some functions themselves are not available: > read.pnm Error: Object "read.pnm" not found I've looked at the file library/R/e1071 with an ascii editor and it seems like the

Encoding() and strsplit()
Dear All, Encoding() goes beyond my understanding. See the example. I would expect from reading the help for Encoding() that strsplit preserves the encoding for each resulting element, but for simple letters it gets lost. Also it seems that an Encoding() cannot be declared for simple letters. They remain in any case "unknown". In paste() "latin1" seems to dominate

vectorization of a loop for mahalanobis distance calculation
Dear all, We have a data frame x with n people as rows and k variables as columns. Now, for each person (i.e., each row) we want to calculate a distance between him/her and EACH other person in x. In other words, we want to create a n x n matrix with distances (with zeros in the diagonal). However, we do not want to calculate Euclidian distances. We want to calculate Mahalanobis distances,

loading of an unwanted namespace
I have a debugging environment for the survival package, perhaps unique to me, but I find it works very well. To wit, a separate directory with copies of the source code but none of the package accuements of DESCRIPTION, NAMESPACE, etc. This separate space does NOT contain a copy of src/init.c Within this I use R --vanilla, attach my .RData file, file, and away we go. That is,
