Given S4 methods [ and [<-, how do I write the Rd-file usage clause for the latter one? What I have now is: \S4method{[}{TimeSeries,TimeDate,missing}(x, i, j, ..., drop) \S4method{[<-}{TimeSeries,TimeDate,missing,ANY}(x, i, j, ..., value) which...

Hi all: since about a month we encountered a problem with R -e command: spaces in the "command" of R -e "command" are no more tolerated. This same issue affects 2.11 patched (05-05-2010), 2.10.1, and...

As I haven't got any replies to my earlier posts about incorrect tick positions in plot and matplot, here is the simplest patch to correct this issue (it fixes both plot with xlim/ylim and matplot). The plot.R...

If you use JNI or rJava, you should start the VM with -Xrs argument, otherwise the descibed things happen as Java catches the Ctrl-C interrupt Dr Oleg Sklyar Research Technologist AHL / Man Investments Ltd +44 (0)20 7144 3107...

Because there is no second thread to do that, R is single threaded. The gc could only be run from within another R API command or macro, but there is none in between. Best Oleg Dr Oleg Sklyar Research Technologist...

Hi everybody, any idea why showMethods fails with the following error when printTo is set to false, i.e. to return the output as a character vector. It works fine if printTo is left default as seen below. The behaviour...

Hi John, sorry for not posting more info. Strangely I get warnings about setClassUnion with numeric in a very special case: if I define it in a clean R session then there are no warnings, however if I load a...

Because there is a % sign, which is stripped out by LaTeX used to build the help system as a comment. Just look at how your example code is output -- the string is unterminated because the matching quote is masked by...

After moving to OpenMPI from LAM, we started to get the following error messages with Rmpi: [hpc01:06981] [[11499,1],0] routed:binomial: Connection to lifeline [[11499,0],0] lost The main script is a lengthy 3-hour long process...

It's not a problem with R, it's just fBasics is buggy! It overrides log and round. Please contact the maintainer of the fBasics package. Dr Oleg Sklyar Technology Group Man Investments Ltd +44 (0)20 7144 3803 osklyar...

Dear list. Has anybody had any issues with ROracle, namely consistently leading to a segmentation fault? One of our oracle databases seems to have certain issues at the moment (do not know what exactly though) and if that one is...

Dear list: I am looking for a good way to create an S4 class that would extend numeric, but would allow NULL instead of data as well. As far as I can see there is no way at the moment...

You should not have started with R/C API without reading this (first link in google): "Writing R Extensions". For your particular question you want pages 72+ and sections 5.9.3 and 5.9.4, possibly further as well...

Dear Yihui, I am sure there are many possibilities available, but I am not looking for a hack and rather for a versatile high-quality solution. It solution should be fast, reliable and developed to a high standard. Moreover, on...

You will need to define several for different combinations of i and j types e.g. ANY,missing; ANY,ANY; missing,ANY or possibly for types like integer, character and logical more or less in the following way: setMethod("[", signature...
