Hi all, I have a function which makes use of missing() to determine which arguments are provided in the call - basically, there are two sets of arguments that map to different strategies the function uses to fulfill its task. After conversion to an S4 generic I've run into the problem that if a method uses extra arguments that are not in the signature of the generic, usage of missing()

Dear R-devel members, I would like to compile a package with two seperate shared libraries. For example, in a package 'foo', a file 'bar.so' built from a distinct set of source files should be installed in addition to the default 'foo.so' (or .dll on windows). Does anyone know about a way to achieve this without having a custom Makefile, e.g. via 'Makevars'?

Hi all, I just stumbled across the difference between explicit and 'automatic' row names for data frames. Is there a quick way to find out if a data frame has automatic row names or not? Of course I know this for data frames that I create myself, but what if a function needs to extract this information for an argument? The following example shows that this property is not easily

Hi all, I am posting this again because I got no reply on r-help. Maybe the devel-list is the right place for this kind of question. I've run into the following problem with Sweave: I frequently run Sweave from a xterm console within an X session owned by a different user, i.e. my colleague is logged in on this computer and I do "su" with my username and start R and Sweave

Hello, I am using R 2.11.0. I have a curious problem where I get a warning in R CMD check which is seemingly not relevant to my Rd file. The warning says : * checking Rd \usage sections ...

Hi all, I use txtProgressBar to monitor progress of large computations. What I miss is the ability to redirect the progress bar to a stream other than stdout, specifically to the message stream. This would be useful for running Sweave scripts: When redirected to stderr, the bar could be visible even though console output is diverted to the output file (and there would be no cluttering of the

Dear all, I am searching for a possibility to view large data sets (e.g. stored in ffdf objects) in a GUI window in a memory-efficient way. So far I looked at gtkDfEdit (package RGtk2Extras) and gdf (package gWidgets). Both operate (as far as I can see) on data frames stored in memory. gtkDfEdit accepts an ff data frame as input, but there is a long delay before it shows up, so I presume the

Hi all, I've run into the following problem with Sweave: I frequently run Sweave from a xterm console within an X session owned by a different user, i.e. my colleague is logged in on this computer and I do "su" with my username and start R and Sweave afterwards. Now, when Sweave comes to a figure chunk, it sees that there is an X server running and tries to show whatever I plot

Hello all, I posted the following bug last week: # These calls work correctly: match(c("A", "B", "C"), c("A","C"), incomparables=NA) # okay match(c("A", "B", "C"), "A") # okay match("A", c("A", "B"), incomparables=NA) # okay # This one causes R to hang: match(c("A",

Hi all, I stumbled across the following, in my opinion surprising, behaviour of read.table: > data <- read.table(stdin(), sep=",") 0: 1, 2, 3 # Some comment 1: > sapply(data, class) V1 V2 V3 "integer" "integer" "numeric" I was surprised to find that V3 has class "numeric" despite its apparent integer value.

Running linux 10.04 ubuntu. Looks like Ubuntu automatically updated to version 2.13. I was running version 2.12 until today. But now I'm getting error messages when I use the require or library command and one of the packages I've downloaded in the past. For example: > require(quantmod) Loading required package: quantmod Warning message: In library(package, lib.loc = lib.loc,

Dear users, I have looked on different sources and found different functions to prompt the user to provide input. However, I couldn't find one that does exactly what I'm looking for. select.list() and menu() are nice because a graphic window appears to prompt the user. However, the user can only choose from a predefined list of choices. readline() and scan() are more free in the

Dear developers, We want to use "\S4method" to document new S4-methods for "[" and "[<-". We use this for other functions/methods and it works without any problem, but in case of "[" and "[<-" we didn't manage to bring this to work. The problem occurs in the development version of our package "distrSim" which can be found

Hi, this is perhaps not so much an issue, but as you are currently working on the Rd parser anyway... When you want to document specific S4 methods for an S4 generic by \S4method{} within a \usage{} environment, and the second (signature_list) argument is "long", be it because you use multiple dispatch, be it because you use long class-names, (or both), one would probably like to be

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 results in the following output: ## S4 method for signature 'TimeSeries, TimeDate, missing': x[i, j, ..., drop]

I was on vacation the last week and wrote some code to run a 500-day correlation between the Nasdaq tracking stock (QQQ) and 191 currency pairs for 500 days. The initial run took 9 hours(!) and I'd like to make it faster. So, I'm including my code below, in hopes that somebody will be able to figure out how to make it faster, either through parallelisation, or by making changes. I've
