problems with postscript device
Hi!
The postscript device in 0.90 does not produce symbols (pch=) as it
should. E.g.:
postscript(file="test.ps",width=8,height=6.4,horizontal=FALSE)
plot(1:10,1:10,pch=1:5)
legend(1,9,letters[1:5],pch=1:5)
dev.off()
The result looks quite different compared to the X-windows version.
The symbol 1 (pch=1) is much to small, while the other symbols
seem to big.
Is it a bug? How can I

size of text and numbers in graphs (PR#349)
Hi!
Since installation of R 0.90 there are problems with the size
of text and numbers also in the x11-device (I reported about similar
problems with the postscript device recently). For numbers and
letters a different size is used:
plot(1:10,1:10,type="n")
text(2,8,"F5F5F5F5F5")
text(2,7,"F5F5F5F5F5",cex=2)
The same problem is also found in the postscript

dataframes and factors
Dear R-List,
I have a dataframe X containing factor f and numeric variable x1, x2, ... I
want to create a new dataframe (or possibly a matrix) that gives statistics
(e.g. sum) for the variables x1, x2, ... in each group defined by factor f.
What is the simplest way to do this?
I tried:
attach(X)
Z <- data.frame(f=levels(f),x1=as.vector(lapply(split(x1,f),sum)))
and stumbled on:

eval(), expression()
Dear R-Users!
My aim is to produce boxplots without the outliers included in the
plot. I started to write a function that looks something like:
myboxplot <-function(x,fa) {
bpdata <- boxplot(x~fa,plot=FALSE)
bpnames <- names(bpdata)
for (JJ in bpnames) {
command <- paste("bpdata$",JJ,"$out <- numeric(0)",sep="");
eval(command)
}

window(): feature request
Dear R-developpers,
currently the function window shows the following behaviour, if start or
end is out of range:
> x <- ts(1:14,start=c(1950,2),frequency=4)
> y <- window(x,start=c(1950,1),end=c(1953,4))
Warning messages:
1: start value not changed in: window.default(x, ...)
2: end value not changed in: window.default(x, ...)
Instead of this I would like it to fill with NAs the

using weights in lm()
Hello!
When I know the vector of the variance of the disturbances (i.e. the
structure of heteroskedasticity), say Var(u_{i})=v_{i},
what is the weights I should use as argument to lm():
M <- lm(y~x,weigths=1/v)
or
M <- lm(y~x,weights=1/(v^0.5)) ???
In the help pages I did not find a clear answer to this question, so
please could someone help me!
Thanks,

skewness, kurtosis
Dear R-Users and Developpers,
Currently R does not include functions to compute the skewness and
kurtosis. I programmed it myself in the following way, but probably
*real* programmers/statisticians can do that better:
mykurtosis <- function(x) {
m4 <- mean((x-mean(x))^4)
kurt <- m4/(sd(x)^4)-3
kurt
}
myskewness <- function(x) {
m3 <- mean((x-mean(x))^3)

biplot
Dear list,
I want to perform a biplot, using customized titels for the x and y axis.
Setting xlab="" and ylab="" resulted in an error, e.g.:

Error in biplot.default(t(t(scores[, choices])/lam), t(t(x$loadings[, :

excuse the repeated mailings..
Our sys.admin fixed one important (NIS) problem and
accidentally simultaneously badly broke part of sendmail's functioning.
Unfortunately, this lasted ~ 40 minutes, and somehow sendmail
just "thought" it had to resend these messages several times (up to 8 x)
that came in during that 40 minutes' period.
Accept our (math.ethz.ch)'s apologies...
