Generalized Additive Model
Hello, I am wondering if someone can direct me to the syntax of the Generalised Additive Model in R? In Splus this is gam(formula, ... inputs would be pretty much the same as glm I suspect..) Any response on that (or what package should I grap) would be appreciated very much. Thanks, Peppy Adi-Purnomo -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Hello again, If I want to have a set of add-ons functions (say: nlme and tseries) loaded to R everytime I run R, do I put command: library(nlme) library(tseries) in the rw1021/etc/Rprofile file? thanks, Peppy -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info",

Hello, I am wanting to download the recent R update off the web. May I assume confidently that R package from the website is virus free? I apologise if this is a very silly question, I just need to convince myself if the site is very hygiene.

Vector-isation
Hi, Suppose I have a by b matrix which a and b are big numbers. How can I convert this matrix into a vector with length of a*b ? By column-wise or row-wise doesnt matter. My R version is 0.64.2.

glm vs lm
Dear Help desk, What is the difference between glm and lm in R? I am so sorry the help pages dont really help me much since they dont have description how R handles the two.

anova
hello, I have a very old R version which calculates anova table for a stream of outcomes say: 1,5,4,3,2,4,5,2 which are grouped into 4 blocks, say A,B,C,D, of 2 say namely X,Y What is the command in R 0.64.2 to do this? My very old R command is anova.table but this command is unkown in R 0.64.2 Thanks, Peppy -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Regression on non linear model
Dear Help desk, I have a model that I believe to be non linear. The relationship is something like: Response = Var1 + Var1^2 + Var1^3 Can I examine this relationship using glm or lm? However, glm or lm gives out pnly 1 coeficient for the model which is on Var1, unless I created some dummy var like (Var2 = Var1^2 and Var3 = Var1^3). Is there any other function handling this relationship?

2 lme questions
Greetings, 1) Is there a nice way of extracting the variance estimates from an lme fit? They don't seem to be part of the lme object. 2) In a series of simulations, I am finding that with ML fitting one of my random effect variances is sometimes being estimated as essentially zero with massive CI instead of the finite value it should have, whilst using REML I get the expected value. I guess

long-standing documentation bug in ?anova.lme
tl;dr anova.lme() claims to provide sums of squares, but it doesn't. And some names are misspelled in ?lme. I can submit all this stuff as a bug report if that's preferred. ?anova.lme says: When only one fitted model object is present, a data frame with the sums of squares, numerator degrees of freedom, denominator degrees of freedom, F-values, and P-values The output of fm1

lme
I am using rw0641. In my continuing quest to understand repeated measures analysis, I again return to lme. I exported the Potthoff and Roy data Orthodont.dat from S-PLUS 4.5 to avoid capture errors and ran the examples in the R help. I imported the data.frame with data <- read.table("Orthodont.dat",header=T) attach(data) and created the objects Orthodont.fit1 <-

how to fix the level-1 variances in lme()?
Dear all, Edmond Ng (http://multilevel.ioe.ac.uk/softrev/reviewsplus.pdf) provides an example to fit the mixed effects meta-analysis in Splus 6.2. The syntax is: lme(fixed=d~wks, data=meta, random=~1|study, weights=varFixed(~Vofd), control=lmeControl(sigma=1)) where d is the effect size, study is the study number, Vofd is the variance of the effect size and meta is the data frame.

Methods for objects inheriting from lme (nlme package)
Dear R developers, One function in my mkin package [1] returns an object that is originally created by nlme(), but contains some additional information. Its class is c("mmkin.nlme", "nlme", "lme"). Now I would like to use the anova() method for lme objects for comparing such S3 objects. Unfortunately, anova.lme currently does not check for inheritance, but

the function lme in package nlme
Dear people, A somewhat clueless question follows: I just discovered that the lme function in contrib package nlme for R, while similar to the lme function in Splus, does not use the cluster function option. This difference does not appear to be documented in the V&R `R Complements' file. I have data which is divided into 6 groups The lme model is of the form (simplified from the actual
