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 Rainer -- Rainer M. Krug, Dipl. Phys.

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, Rainer -- Rainer M. Krug,

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) Rainer -- Rainer M. Krug, Dipl. Phys. (Germany), MSc

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.

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

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.
