local source packages install from within R session - cross-platform
I realize that others have struggled with this issue...i.e. http://tolstoy.newcastle.edu.au/~rking/R/help/05/01/9826.html i am on os.x 10.4 w/ R2.2, and am (perhaps foolishly) also on this quest... i would like to be able to install downloaded source (tar.gz'd) files from within an R session, and have it work in a X-platform way..i am often not connected to the internet and have libraries

Basic package structure question
At the encouragement of many at UseR, I'm trying to build my first real package. I have no C/Fortran code, just plain old R code, so it should be rocket science. On a Linux box, I used package.skeleton() to create a basic package containing just one "hello world" type of function. I edited the DESCRIPTION file, changin the package name appropriately. I edited the hello.Rd file.

Another R syntax question
The file src/library/base/R/print.R contains this line: x0 <- xm[okP]==0 != (as.numeric(Cf[okP])==0) I didn't know R allowed that, and I wonder if it is deliberate? In mathematics, you would expect x = y not= z to mean (x = y) and (y not= z).; In R, it is parsed as (x == y) != z. While I have to admit that the spacing around == and != in

na.action in randomForest
The help page for randomForest shows na.action=na.fail as a parameter, and does not describe other possibilities for na.action. I have a regression problem, with about 1000 rows in my data frame, and with an NA in occasional predictor variables, in about 5% of rows. I would like to have all rows included in the analysis, to the extent possible. (That seems to be possible in rpart, for example.)

checkS3methods() change
Hi, I'm using rw2000dev.exe (Win32) built on August 14. If this isn't already planned, can I suggest that when checkS3methods() (called by R CMD check) fails because of a syntax error in a dependent package listed in the DESCRIPTION file of the main package being checked, it would be nice if checkS3methods() reported which dependent package caused it to fail? Running R CMD check on my

length() misbehaving?
I'm having a weird problem with length(), in R1.6.1 under windows2000. I have a dataframe called byyr, with ten columns, the first of which is named cnd95. summary(byyr) shows that byyr$cnd95 contains the factor level "tr" 66 times. Also, when I enter byyr$cnd95 at the command line, I can count 66 "tr" elements in the resulting vector. However, when I enter n95trt <-

font size in console
I'm using R in a statistics class, and when I project the console, the font is smaller than ideal. I've checked the faq's, the manual, and the help system as best I can, and I don't see how to change the font size. Can it be changed from within a session, or will I have to ask the folks who installed the program on the server I use in classes to set it (assuming that can be
