hist(rbinom(1000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,300)) gives a histogram with "touching bars" hist(rbinom(100000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,30000)) gives a histogram with space between the bars. is there a way to control the space betweent he bars easily? -- Erich Neuwirth, Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at

In some languages there is a function gensym() which returns a new unique name (in the current environment). This is quite helpful when one has to do temporary assignments. I could not find such a function in R.

Hi, I'm trying to combine a VBA macro and a R package. I've installed the R-(D)COM and the R-excel interface by Neuwirth. They seem to work both. However I would like to display the r-generated data in an Excel sheet as an array but I don't manage. Here is an example of my source: Sub doR() Call RInterface.StartRServer Call RInterface.RRun("library(mdnn)") Call

I wrote a R script say called computeCovarMatrix.R and i want to call and run this piece from Excel visual basic. does anyone know how to do that? thanks, KZ [[alternative HTML version deleted]]

I have a big contingency table, approximately of size 60*2*500*500, and I need to count the number of cells containing a count of 1 for each of the factors values defining the first dimension. Here is my attempt: tab1<-with(pisa1,table(CNT,GENDER,ISCOF,ISCOM)) tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0)) tab3<-apply(tab2,1,sum) Computing tab2 is very slow. Is there a faster

Dear all, I have recently experienced something with the function order I cannot explain: The help(order) (which I admit having overlooked before) rises even more my confusion... The following lines made me think order() was returning the 'order' each value in a vector would take when sorted. > a <- c(4.1, 3.2, 6.1) > order(a) [1] 2 1 3 Doing > plot(a,

I have problems with Rpad and R 2.10.0 (Windows XP and Windows 7, browser is Firefox) Just starting Rpad by library(Rpad) Rpad() opens the browser and displays the .html files and the .Rpad files in my home directory, but these files do not have links and are not clickable. Doing the same in R 2.9.2 gives clickable links in the browser. Furthermore, in both cases an empty graphics window

Is there code for bivariate kernel density estimation? For bivariate kernels there is kde2d in MASS kde2d.g in GRASS KernSur in GenKern (list probably incomplete) but none of them seems to accept a weight parameter (like density does since R 2.2.0) -- Erich Neuwirth, University of Vienna Faculty of Computer Science Computer Supported Didactics Working Group Visit our SunSITE at

I do not know if this has been reported already (I searched the headers of the recent messages to r-devel) It seems that 'example' in R 2.11.0 has a problem when the help file does not contain any example.

Dear R users, I've just posted a similar question about Illustrator. This time I would like to export the results of my statistic tables and my dataframes into Excel files. Up to now I've used write.csv(), but I have to resave every file in .xls in Excel. I would like to know if there is a function or package to export directly into *.xls. I have found xlsReadWrite which would be
