sub- and superscript in plot labels
Dear List,
I need to add a subscript and a superscript to some of the ions in the
labels on some plots.
I have got to here but now I'm stuck:
plot(1:10, xlab = expression(paste("nm SO"[4], " ", mu, "eq cm"^{-2}, "
yr"^{-1})))
Which gives almost what I require. No matter what I tried, however, I
could not get bot a sub script *and* a superscript

merging dataframes
Dear List,
I often have to merge two or more data frames containing unique row
names but with some columns (names) common to the two data frames and
some columns not common. This toy example will explain the kind of setup
I am talking about:
mat1 <- as.data.frame(matrix(rnorm(20), nrow = 5))
mat2 <- as.data.frame(matrix(rnorm(20), nrow = 4))
rownames(mat1) <- paste("site",

problems when installing R in Fedora core 4
Hi, I got a problem when installing R in Fedora core 4. When I ran
.configure, it gave the following error message:
configure: error: --with-x=yes (default) and X11 headers/libs are not available
Could anyone tell me what's wrong? Am I missing some package in Fedora?
Thanks a lot for your help.

graphic of hierachical clustering
Hi all,
I would like to save the dendrogram of a hierarchical clustering.
Let reshc the result of the fucntion hclust(). To save the dendrogram,
I can use the function postscript:
postscript(file="hc605.ps")
plot(as.dendrogram(reshc),horiz=T,ylab="",main=" ")
dev.off()
Using the functions plot and as.dendrogram, it is possible to obtain an

as.character and a formula
Dear list,
given this formula:
> fmla <- formula(y1 ~ spp1 + spp2 + spp3 + spp5)
> fmla[[3]]
spp1 + spp2 + spp3 + spp5
is this the intended behaviour of as.character:
> as.character(fmla[[3]])
[1] "+" "spp1 + spp2 + spp3" "spp5"
? Where does the extra "+" come from?
> as.character(fmla)

I was wondering whether a package that can perform dynamic linear models on
times series data was available for R?
Many Thanks,

ts function
hello
I read "Practical Time Series" (Gareth Janacek; 2001) and they presented
e.g the
smoothing functions msmooth(x,k) or the bivariate function
crosscorr(x,y,k),
but both didn't work on my machine. I only load the ts library, is
another
library necessary or did this function change since 2001? Is there a
more recent and detailed manual for ts?
thanks, cheers Martin

Computting statistics on a matrix with 2 factor column
Hello,
I suppose this is a basic question but couldn't find a solution.:
I have a large matrix with let say 3 columns:
V1 V2 V3
a x 2
a x 4
a y 8
b z 16
and I want to compute some statistics based on
the levels resulting form the combination of the two first columns
e.g.:
SUM->
V1 V2 V3
a x 6
a y 8
b z 16
Thanks for your hints .

Sweave and multiple graphs
Dear list,
I am using Sweave to build a small report. I want to produce a series of
figures, each figure containing a number of plots and then have them
included in the Sweave file.
An example would be to :
postscript(file = "ANCbwplot%03d.eps", onefile = FALSE, other options...)
oldpar <- par(mfrow = c(2,2))
....
do lots of plots to produce a number of eps files
....

plotting results from leaps library
Hi
In trying to fit a linear model , I use the leaps() function to determine wich predictors I should include in my model.
I would like to plot the Mallow's Cp criteria against p with the indexes of selected model variates as points labels
Is there already such a function? (I could not find it)
