suggestion for example for base:naresid
Dear list:
since it took me a little while to figure out how to make use of naresid, I thought that
the below R code might be useful as an example on the help page.
Regards,
Markus
# generate some data
x1 <- runif(20)
y <- 10 + 5*x1 + rnorm(20)
summary(lm.0 <- lm(y ~ x1))
# append some NA's to y
y <- c(y, rep(NA, 5))
# generate some further x1s
x1 <- c(x1, runif(5))

unresolved symbols in growth and repeated libraries
I am having trouble using Jim Lindsey's libraries because of unresolved
symbols. I am currently using R 0.65.0, but had this problem in earlier
releases as well. I have a RedHat 6.0 Linux on i386 and use egcs
(upgraded to that distributed with rawhide, after first failures with
the libraries):
egcs-g77-1.1.2-19
egcs-1.1.2-19
Installation of the libraries works but on loading

R-Latex question
Hi, maybe my question is not typical. I want to make R table-kind output to
be readable immediately in Latex but I am struggling with symbol '\' needed
for instance in '\hline'. For example when 'Table' is a matrix class object:
cat("&",Table[1,1], "&",Table[1,2], "\n");flush.console()
cat("\hline \n");flush.console()

weighted kernel density estimate
Dear R-users,
I intend to do a spatial analysis on the genetic structuring within a
population. For this I had thought to prepare a kernel density estimate
map showing the spatial distribution of individuals, while incorporating
the genetic distances among individuals. I have a dataset of locations
of N unique individuals (XY-coordinates) and an NxN matrix with the
genetic distances given as a

using poly in a linear regression in the presence of NA f ails (despite subsetting them out)
This smells like a bug to me. The error is triggered by the line:
variables <- eval(predvars, data, env)
inside model.frame.default(). At that point, na.action has not been
applied, so poly() ended being called on data that still contains missing
values. The qr() that issued the error is for generating the orthogonal
basis when evaluating poly(), not for fitting the linear model itself.

pinning R packages to unstable?
Dear Debian R users,
This is more of an apt question rather than R. I have a testing Debian
system, but would like to use the unstable packages for R, *without* using
the -t flag in apt-get. I think this is done by using a 'pin' rule in
/etc/apt/apt.conf, but don't understand how this should be done. Can
somebody provide an example please?
Cheers,

Fitted Value Pareto Distribution
I would like to fit a Pareto Distribution and I am using the following codes.
I thought the fitted (fit1) should be the fitted value for the data, is it
correct? As the result of the "fitted" turns out to be a single value for
all.
fit=vglm(ycf1 ~ 1, pareto1(location=alpha), trace=TRUE, crit="c")
fitted(fit)
The result is
fitted(fit)
[,1]
[1,] 0.07752694

R-beta: adjusting y-axis scale with multiple lines in plot
Hello --
I am plotting multiple densities in a single plot. If the max of a new
density (added with 'lines()') is sufficiently larger than that of the
one first plotted (using 'plot()'), the new density is cut or
trucated off of the figure. Is there a simple way of adjusting the
yscale after all lines have been added?
Or is the procedure to be used to first estimate all

Std Err on Concentration measures
Hi,
I'm using the ineq package to calculate some concentration measures (Gini, Herfindal, ...) and I was wondering if there's around also a function to calculate standard error on these measures. If not, is anybody aware of where I can find a reference on this point?
Thanks.

Sweave special token \\ from R to latex
Dear helpeRs,
I would like to specify a newline command in R and pass it to latex
via Sweave such that it corresponds to latex' \\ command. But that
doesn't seem to be possible. If I Sweave the \n character, it just
makes a new line in latex but not the \\ command.
Is there a way such that the following code would result in latex in
blablabla \\ blablabla on different line

poly() in lm() leads to wrong coefficients (but correct residuals)
Dear all,
I am using poly() in lm() in the following form.
1> DelsDPWOS.lm3 <- lm(DelsPDWOS[,1] ~ poly(DelsPDWOS[,4],3))
2> DelsDPWOS.I.lm3 <- lm(DelsPDWOS[,1] ~ poly(I(DelsPDWOS[,4]),3))
3> DelsDPWOS.2.lm3 <-
lm(DelsPDWOS[,1]~DelsPDWOS[,4]+I(DelsPDWOS[,4]^2)+I(DelsPDWOS[,4]^3))
1 and 2 lead to identical but wrong results. 3 is correct. Surprisingly

Problem loading library Design
I have used library Design (Frank Harrell) in the
past but when I tried this week, I get :
> library(Design)
Error in eval(expr, envir, enclos) : Object
"formula.default" not found
I updated to the latest version of the library
(2.0) with the same result. My version of R may
not be the latest but it's recent (and I probably
changed since using Design for the last time) :

using weighted.mean with tapply()
I am trying to calculate the weighted mean for a of 10 deciles and I
get an error:
> decile <- tapply(X=mat$trt1m, INDEX=mat$Rank, FUN=weighted.mean, w=mat$mcap)
Error in FUN(X[[1]], ...) : 'x' and 'w' must have the same length
All three of my inputs have the same length, as shown below, and the
weighted.mean calculation works by itself, just not in tapply()

R + Linux
Dear all;
I'm planning to install Linux on my computer to run R (I'm bored of
W..XP). However, I haven't used Linux before and I would appreciate,
if possible, suggestions/comments about what could be the best option
install, say Fedora, Ubuntu or OpenSuse which to my impression are the
most popular ones (at least on the R-help lists). The computer is a PC
desktop with 4GB RAM and

help with gls
Hello R-users,
I am using gls function in R to fit a model with certain correlation
structure.
The medol as:
fit.a<-gls(y~1,data=test.data,correlation=corAR1(form=~1|aa),method="ML")
mu<-summary(fit.a)$coefficient
With the toy data I made to test, the estimate of mu is exactly equal to
the overall mean of y which can not be true.
But, if I make a toy data with y more than two
