Hi all, is there an easy way to build up a data frame by sequentially adding individual rows? The data frame consists of numeric and character columns. I thought of rbind, but I ended up with numeric values for the character columns. Pascal

Hi all, Given a number of points (x,y) in a plane, I'd like to plot a map of polygons, so that 1) each polygon contains exactly one point 2) the polygon defines the area for which this specific point is closer than any other point. It's a bit like a map of areas "influenced" by that point, and it's obviously a matter of intersecting the perpendicular bisectors

savehistory writes all the executed lines from the session. How can I write everything (executed lines and output) from the active session to a file? Using Edit | Select All then Edit Copy, I can copy everything to the clipboard and write the whole thing to a file manually. If I just used the clipboard, I can paste the whole content into another edittor (for documentation). Is there a way to

Hi all, Is there a function to check if a particular value is contained in a vector? I've looked at grep in the hope that I could use a Perl-like syntax, but obviously it's different... I'd like to do something like: y <- c("a","b","c") if("a" in y) { # "a" is not in y } Also, is there a way to

Dear all, I hope this is the right mailing list for my question -- I felt that this was too technical for R-help. I am trying to compile R-2.4.0 on a HP-UX system: ./configure MAKE=gmake --prefix=$HOME --without-x --without-tcltk --disable-R-profiling --without-readline --disable-multibyte R is now configured for ia64-hp-hpux11.23 Source directory: .

Hi all, I am playing around with latin squares, and wrote a recursive function that searches for valid combinations. Apart from the fact that there are very many, I run into troubles beginning with size 10x10 because the recursion depth becomes too large (max of 10x9-1=89 in this case). Why is this a problem? Isn't there enough space allocated to the stack? Can this be increased? The

Hi all, I wonder how to correctly write the following expression (it's the axis label in a plot command): ylab=expression(y' == y - bar(y) ) Somehow the single quote in y' is causing the problems, I guess because it is interpreted as a quote... Does it have to be escaped? But how? Thanks for your help Pascal

I am trying to plot a figure within a figure (an inset that shows a closeup of part of the data set). I have searched R-help and other sources but not found a solution. What I would like to do is (1) produce a plot (2) specify a window that will be used for the next plot (in inches or using the coordinate system of the plot produced in (1) (3) overlay a new plot in the window specified under (2)

Hi all, I repeatedly encounter the following problem: After importing a data set into a data frame, I wish to set a column with numeric values to be a factor, but can't figure out how to do this. Also, I do not wish to write as.factor(x) all the time. I can create a new vector with x <- factor(x), but the new vector resides outside the attached data frame. Pascal > attach(ngrad)

Hi Everyone, I am a beginner running R 2.9.2 under Ubuntu and typically use Emacs w/ESS. However, I am confused with history() command. When I issue command history() in Emacs within an R session, this is what get: > history() Error in savehistory(file) : no history available to save Similarly, history(max=10) command gives the same error message. However, there is this In/Out Menu in the

Hi, is there a platform independent way to log a complete R session (input + output + warnings + errors + ???) into a text file? I can use sink(file, split=T) and savehistory() but it is quite cumbersome to merge the files and still there is some loss (eg. warnings). I wondered that I only found this thread from 2003(!) related to this topic:

Hi all, I'd like to extract a value from an ANOVA table, but experience the following problem: ### This works: > s.pseudo <- summary(aov(m ~ block + mix*graz,data=split1)) > s.pseudo Df Sum Sq Mean Sq F value Pr(>F) block 2 1114.66 557.33 4.4296 0.04192 * mix 1 6.14 6.14 0.0488 0.82956 graz 2 1.45 0.72 0.0057 0.99427 mix:graz

Hi all, I am trying to produce some panels with dots in an X/Y plane where the diameter of the dots indicates a Z value (like e.g. earthquake maps where dot sizes indicate magnitudes and X/Y the location). This works fine with xyplot, e.g.: xyplot(1:3~1:3,cex=1:3,pch=16) However, when I do this with a panel variable, e.g.: x<-rep(1:3,5) y <- rep(1:3,5) sz <- rep(1:5,each=3) grp

Hi, > history() gives Error in savehistory(file) : no history available to save although I can scroll throu history with C^uparrow an C^downarrow. How can I make history() work and/or show the current history in a file, so that I can choose from previous commands? The web did not throw up anything useful. TIA --Christian -- Christian W.

Dear all, I am not sure if this mail is for R-help or should be sent to R-devel instead, and therefore post to both. While using nlrob from package 'robustbase', I ran into the following problem: For psi-functions that can become zero (e.g. psi.bisquare), weights in the internal call to nls can become zero. Example: d <- data.frame(x=1:5,y=c(2,3,5,10,9)) d.nlrob <-

Hi all, I ran into a problem in some of my code that could be traced back to 'mean' sometimes returning NA and sometimes NaN, depending on the value of na.rm: > mean(c()) [1] NA > mean(c(NA),na.rm=T) [1] NaN However, I don't understand the reasoning behind this and would appreciate and explanation. I understand that the mean of an empty vector is not definied, but I

Hi all, I could not find a way to add the dashed horizontal separator line to the top panel of a coplot (the one indicating which panel belongs to which range of the given variable a in y~x | a). This line should separate the ranges plotted in a row of panels in the panel matrix below (hmmm, hope this is reasonably clear). I like it because it enhances readability. I'll try a sketch: >

Dear R-user, I already received quite a lot of replies to this mail and like to do a preliminary sum up. A few were sceptical about the use of such a beginner mailing list. The arguments were that people starting with R will only stay subscribed for a short time until they reached the R-help "level" and therefore only beginner will teach beginner how to use R. But as far

I'm using R from a Linux command prompt, and am logging the whole session by tee'ing the R invocation line. ie. R | tee -a Rlog.txt Is there a better way to log all the session input and output from within R? Stan Smiley stan.smiley at genetics.utah.edu
