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,

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

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.

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 ?...

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: expert | xx | seeds | r.squared | slope | intercept Thanks in advance, Rainer library(reshape) rsqs <- as.data.frame(

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

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)

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

Hi I have problems installing R 2.1.1. from rpm (R-base-2.2.0-1.i586.rpm) on SuSE 10. It installs fine, all dependances are OK (at least Yast does not complain) but when I try to run R, it gives the following error message: symbol lookup error: /usr/lib/libblas.so.3: undefined symbol: _gfortran_filename and R quits. blas version: 3.0-926 Any help appreciated, Rainer -- -- Rainer M.

Hi I installed R 2.2.0 from source and want to use install.packages but it doesn't work. http_proxy is set to http://proxy.sun.ac.za:3128 but it still can't connect to the repository.

Hi I am using R 2.2.1 under Linux (SuSE 10) and would like to know if it is possible to create graphs, i.e. jpeg(filename=fn) try( coplot( mor$I_Morisita ~ mor$Year | mor$RunStr, show.given=FALSE) ) dev.off() from a text console? It gives me an error message on the jpeg() command: Error in X11(..snip..) unable to start device jpeg In addition: warning message: unable to open connection to

Hi I have the following loop and would like to vectorize it. Any ideas if it is possible? Thanks, Rainer Tha Loop: for (i in 2:Result$NoSims) { ppp <- runifpoint(Result$NoPlants) K <- Kest(ppp) Result$LSim[i,] <- sqrt(K$iso / pi) - K$r CM <- (Result$LSim[i,] * Result$LSim[i,]) / abs(K$r[2] - K$r[1]) Result$SigCM[i] <- sum(CM, na.rm=TRUE) print(i) flush.console() }

This code below produces empty XXX.png files - if I use plot(), it works and if I enter the commands png(filename=fn) bubble(positions, do.sqrt=FALSE, main=q) dev.off() manually, it works as well. I am lost - any help appreciated. The weird thing is that it worked before I made some changes... (I don't have a copy of the working version...). R version: platform i686-pc-linux-gnu arch

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

Hi I am using R 2.2.0 under SuSE 10 I want to use lm() to get the slope and intercept for several daatasets and store them in a database. So far so good - but how do I extract the slope and the intercept from the result from lm()? my code looks like this: lmNNDens <- lm(log(DensNN$MeanNN) ~ log(DensNN$MeanDensity)) anovaLM <- anova(lmNNDens) Results$slope[No] <- ???lmNNDens???

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.

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

Dear R-help, I have a loop, which is set to take about 26 hours to run at the rate it's going - this is ridiculous and I really need your help to find a more efficient way of loading up my array gpcc.array: #My data is stored in a table format with all the data in one long column #running though every longitute, for every latitude, for every year. The #original data is sotred as
