seqN
I have been using a function seqN <- function(N) {if (0==length(N)) NULL else if (N<=0) NULL else seq(N)} in for loops when I want no looping in the case of a zero value: for (i in seqN(m) ) ... Since seqN(0) returns NULL this results in for doing no loops (which is much more convenient than always checking for m==0). It seems that a function like this should be defined in R (and S) but

Direct Method Age-Adjustment to Complex Survey Data
Hi everyone, my apologies in advance if I'm overlooking something simple in this question. I am trying to use R's survey package to make a direct method age-adjustment to some complex survey data. I have played with postStratify, calibrate, rake, and simply multiplying the base weights by the correct proportions - nothing seems to hit the published numbers on the nose. I am trying to

upgraging R from 2.9.0 to 2.9.1
I am still running 2.9.0 and came across a package that was built with 2.9.1. I got a warning upon loading the package. I tried to launch a function from such a package. It seems to hang up. I can't believe it takes forever. I am resolved to upgrade my R version to the newest one. But on a Windows box I do not know how to unistall the current version in advance of installing the new one.

Datasets in R
I?m trying to find datasets that will give me residuals, after applying the lm function, with no normality, non linearity, and heteroscedacity so I can try to exemplify those cases in the linear regression model. Can you give any advice on what datasets would be appropiate? I can?t use the ones in the alr3 package because those have already been seen in class. Thank you very much :-) natorro

variable transformation for lm
Hello, I am doing a simple regression using lm(Y~X). As my response and my predictor seemed to be skewed and I can't meet the model assumptions. Therefore I need to transform my variables. I wanted to ask what is the preferred way to find out if predictor and/or response needs to be transformed and if yes how (log-transform?). I found a procedure in "A modern approach to Regressoin in

question about boxplot
Here is a question from an old guy: I want to use the boxplot function as follows: boxplot( p.prop ~ R + bins ) This command makes nice boxplot for the factor "R" crossed with the factor "bins". I am having alot of trouble getting control of the labels on the X axis. I want to control it more by specifying what the labels are, controling the 'size' of those

Question about "generic" USB <=> Serial Port kernel drivers...
OK, I am running CentOS 6 on my Laptop and Desktop, presently kernel version 2.6.32-696.20.1.el6.x86_64 (yes, a version or so out of date -- I'll probably do an update soon -- non-trivial since my Internet connection is via dialup). I recently bought a couple of Adafruit Arduino compatibles, a Flora and a Metro 328. Hooking up the Flora and the Metro to a Raspberry Pi running Raspbian

R 2.9.0 slower than R 2.8.1 for the data.frame function
Dear developers, I have noticed difference in computation time for the data.frame function between R2.9.0 and R2.8.1. The older release is more efficient: typically, R2.9.0 spends three more time in the data.frame function. Therefore, when many calls of this kind is done inside a function, the additional time spent with R2.9.0 may be several minutes. Looking at the profiling results (see file

US county map question
Hi R-help: I'm just an old guy and new to this list... But have been using R for years now. I want to make a map of counties in the US with shaded colors that depend on the level of variable "Y" that I want to map. I have the US county and state fips codes and the Y variable. How do I do this? Please reply to pzs6@cdc.gov Thanks, Phil Smith pzs6@cdc.gov [[alternative HTML

state map question
Hi R-Help: I want to produce a map of the US with different colors for selected states. I installed the map package, and then used: library(maps) I can see that by using map( 'state' ) you get the state boundaries, also. How do I fill in different colors for the different states? I see there is a col parameter for map, but can't see how to get it to work! Please reply

difference between 2 dates: IN MONTHS the way Mothers compute it
Hi R-people: I need a function to compute the number of months between 2 dates, in the same way a mother would do it. For example, if a kid is born on February 6, the number of months between that date and March 7 is exactly 1 month, although it is only 29 days. Thank you!
