Hi all, We are facing a problem while introducing ourselves to Reshape package use. Melt seems to work fine, but cast fails when we use mean as fun.aggregate. As you see here, length and sum work fine, but mean throws this same error whatever dataset we use. > cast(aqm, month ~ variable, length) month ozone solar.r wind temp 1 5 26 27 31 31 2 6 9 30 30

Dear R users, About a year ago Deepayan offered a suggestion to incorporate error bars into a dotplot using the singer data as an example <<http://finzi.psych.upenn.edu/R/Rhelp02a/archive/63875.html>>. When I try to utilize this code with a grouping variable, I get an error stating that the subscripts argument is missing. I have tried to insert them in various ways, but cannot

Hi All, I need to sample a vector ("old"), with replacement, up to the point where my vector of samples ("new") sums to a predefined value ("target"), shortening the last sample if necessary so that the total sum ("newsum") of the samples matches the predefined value. While I can easily do this with a "while" loop (see below for example

Hi All, I am writing a simulation that examines the effects of species extinctions on ecological communties by sequentially removing individuals of a given species (sometimes using weighted probabilities) and replacing the lost individuals with species identities randomly sampled from the remaining individuals. Thus I use two dataframes. One contains all the individuals and their species

Dear All, I am hoping to implement a barchart using trellis graphics where all elements have a line width of 2. Using trellis.par.set(), I am able to make most elements lwd=2, but not all. In particular, the top of the box (above the upper most strip) and the left y-axis remain one point. Code with a barchart() example is below. Any advice would be greatly appreciated. Thanks for your

Dear R community, Since upgrading to R v.2.6.1 and re-installing package Hmisc (binary for Mac OS X v.3.4-3), I have been getting a error when trying to make xYplots: >plotcv<-c(34.88, 41.51, 45.81, 51.05, 51.66) >plotcv.se<-c(2.406551, 3.071291, 4.331407, 3.213873, 4.838150) >month<-c(6, 7, 8, 9, 10) >library(Hmisc) >xYplot(Cbind(plotcv, plotcv + plotcv.se,

I'm getting an anomalous result from using the itemize command in a documentation file. My usage is something like \itemize{ \item Melvin \item Irving \item Clyde \item Fred } (This was place inside ``\details{ }''.) (Previously I had enclosed the text following each item in braces but that gave even worse results.) The package appears to install OK; i.e. the command R

Full_Name: Philippe Grosjean Version: 2.6.1 OS: MacOS X; Windows XP Submission from: (NULL) (81.243.237.235) Last output from capture.output() is truncated if it does not end with a carriage return: > capture.output(cat("text\n")) # Fine [1] "text" > capture.output(cat("text")) # Missing output! character(0) >

This only happens if 'file' is a text connection, and is the expected behaviour in that case: you cannot capture an incomplete line to a text connection. There seems no reason to break the documented behaviour in other cases to change something that you consider to a bug when file=NULL and the user does not produce complete output. It would be possible to make use of isIncomplete()

help(letters, htmlhelp=TRUE) fails. Under the Mac OSX gui, the message is 'Help for the topic "a" was not found.'

Dear R users, I need to reorder a dataframe using 3 variables for the determine the sorting order. When I create a simple dataframe to test the method, things work as I expected: a1 <- rep(1:10, each=8) a2 <- rep(rep(1:2, each=4), 10) a3 <- rep(c(1:4),20) (a <- data.frame(a1, a2, a3)) for each combination of a1 and a2, a3 is increasing t <- order(a$a1, a$a2, rev(a$a3)) b

Yes, I'm aware of this, but one of the programs that got installed for me, like i686-apple-darwin8.10.1-gcc-4.0.1, was not getting the program prefix, and was getting used by gcc.

Dear R people, I have recently started using rJava to interact with Java code that I have written and am finding it a very useful bridge. Thanks! I have now run into a problem I can't figure out. If I edit and recompile my java source code I would like to force rJava to reload the modified java class. However even doing: .jinit(force.init=TRUE) To restart the jvm doesn't seem to do

Thank you for your quick reply and for only indirectly scolding me for abusing the RBugs list. :-) However, I do think there is something funny in the 2.7.0 docu (or in the code). Things behave as expected and explained by you for version 2.6.0/2.6.1, but in the development version 2.7.0 (which I was using) the output is different (see below). The CHANGES file does mention some changes about the

Hi there, I have a *really* weird issue with rspec on rails: Given a time meridian formatted using %p When I run `rake spec` the time meridian is converted to lower case: expected: "Today 08:00 PM", got: "Today 08:00 pm" Yet when I run `rake spec:models` and `spec -cfs app/models` the specs pass, ie the the time meridian is in upper case. Anyone got any ideas how I
