specify point shape for ggplot (equivalent to pch)?
Hi
is it possible to specify the shape of the point to be used in ggplot
(as with pch in plot)? I couldn't find anything in the help.
Thanks

Update to Dillo browser question
Hi
I asked about if there is any way of opening URLs from the help browser
in the same window of the same dillo browser - here is the answer.
Just to reiterate: dillo is for me the perfect browser for the help of R
when you use ?...

Compare linear regressios for significant differences of the slopes
Hi
I have (8 measures * 96 groups) = 768 datasets for which I did linear
regressions using lm().
Now I want to compare the slopes for each of the 8 measures in each of
the 96 groups. As I understand , I can not use
> anova(lm1, ..., lm8)
as the lm1 ... lm8 are based on different datasets.
I also read in previous discussions in this list, that I can see if the
slope +- stddev(slope)

transforming factor back to numbers
Hi
I generate a new dataframe by doing:
npl.agg <- aggregate(npl$DensPlants, list(year=npl$year, sim=npl$sim),
mean, na.rm=TRUE )
Now I want to plot it by using
coplot(npl.agg$x ~ npl.agg$year | npl.agg$sim, type="l")
but, as npl.agg$year is seen as a factor, the order of the points on the
x-axis (time axis) does not follow the numerical sorting 1...100, but
rather the text

problem with putting objects in list
Hi
I use the following code and it stores the results of density() in the
list dr:
dens <- function(run) { density( positions$X[positions$run==run], bw=3,
cut=-2 ) }
dr <- lapply(1:5, dens)
but the results are stored in dr[[i]] and not dr[i], i.e. plot(dr[[1]])
works, but plot([1]) doesn't.
Is there any way that I can store them in dr[i]?
Thanks a lot,

Beginners manual for emacs and ess
Hi
I heard so much about Emacs and ESS that I decided to try it out - but I
am stuck at the beginning.
Is there anywhere a beginners manual for Emacs & ESS to be used with R?
even M-x S tells me it can't start S-Plus - obviously - but I want it to
start R...
Any help welcome (otherwise I will be stuck with Eclipse and R)

Calculating mean together with split
Hi
I have a table called npl containing results of simulations.
It contains about 19000 entries and the structure looks like this:
NoPlants sim run year DensPlants
1 6 lng_cs99_renosterbos 1 4 0.00192
.
.
.
it has 43 different entries for sim and year goes from 1 to 100, and run
from 1 to 5.
I would like to calculate the mean of DensPlants for each

density() with from, to or cut and comparrison of density()
Hi
the function density() does normally integrate to one - I've checked it
and it works and I also read the previous threads.
But I realised that it does not integrate to one if I use from, to or cut.
My scenario: I simulated densities of a plants originating from an sseed
source at distance zero. Therefore the density of the plants will be
highest close to zero. Is there anything I can do

fixme:imm:ImmReleaseContext message - what should I do?
Hi
When I run a program I've written with Delphi7, I get several of the
following messages:
fixme:imm:ImmReleaseContext (0x10020, 0x403b9e80): stub

.
The program works - but is there anything I can do to avoid these messages?

Combining factors
Hi
I know this is a basic question and I know I have done it before but I
can't find the answer any more.
I have a data set, say:
F1, F2, Value
F1 and F2 are Factors.
I would like to plot
plot(TheCombinationOf(F1, F2), Value)
I remember there was a function for TheCombinationOf() but I don't
remember the name.
I could create a new factor based on F1 and F2, but I would prefer the

exporting a table to latex
Hi
I am using the latex() command from the Hmisc package to export table
to latex. For formating of the values, I use the format() function. But
I don't manage to get the format of the values right: I don't want
scientific notation, but if I say scientific=FALSE, I get many digits
after the decimal point which I can not control with digits=... and
nsmall=... in the format command.

simplification of code using stamp?
Hi
I have the following code which I would like to simplify. Id does linear
regressions and returns the r-squares, and the coefficients.
It runs slow, as it is doing the regressions for each - is it possible
to get the values in a dataframe which looks as follow:
