gsub difficulty
Greetings R-ians: I know what doesn?t work but I don?t know why, nor how to remedy things. I have a character string containing "." which I want to replace with " " gsub(".", " ", file.label) replaces the every character with a blank. However gsub(".xls", " ", file.label) replaces ".xls" with a blank as expected. It appears

help with my sloppy syntax
R-ians: After some effort I coerced my code to do what I want but my syntax is a kludge. Suggestions on more elegant syntax? par <- NIM.results$par do.call("Draw.NIM.POD.curve", list(par[1], par[2], par[3], par[4], par[5], a.hat.decision, .... et cetera ... It seems that I should be able to avoid defining the variable "par" and then specifying each of its elements,

Which R version created a package?
Greetings, R-ians: I would like to know which version or R was used to create a given package. I think I remember seeing that topic discussed recently but cannot find it among my notes. Can anyone tell me how to determine which version of R created a package? Thanks. Charles Annis, P.E. <mailto:Charles.Annis@StatisticalEngineering.com> Charles.Annis@StatisticalEngineering.com

control L to clear the Rgui screen in Windows
Greetings R-ians: Searching the Searchable Mail Archives I discovered that ctrl L will clear the Rgui screen, which is what I'd like to do from a print (or some similar) statement. Is there a mechanism to use the ctrl L clear-screen sequence in a script, or print statement? Thanks for your counsel. Charles Annis, P.E.

string problems with "\\" (Windows)
Greetings, R-ians: I'm using R 2.3.1 on WindowsXP. I need to find the name of a file at the end of a sting that contains the path + file, with the problematic "\\" as separators. The string looks something like this: "C:\\Documents and Settings\\myName\\My Documents\\R Projects\\Project1\\file.name.csv" What I want is "file.name.csv" Currently I use the

sporadic slow/non response, problems copying to sent folder
After experiencing these symptoms through many of the release candidates, we've been at v1.0.0 now for a few weeks, and they're still there. Perhaps a config issue with my setup (mbox locks?). It's really too disrupting to continue using this way. I've included symptoms, client info, mta info, log entries and config file. What other information can I provide? Please

trouble with character \u00e2
Greetings R-wizards: For historical reasons I have filenames with the character "?" and have successfully used "\u00e2" in its place, with the hoped-for result on all my on-screen plots. However since R2.7.0 I have trouble with savePlot() when the file name includes that character as it does in this example: savePlot(paste("diagnostic ? vs a ", file.label,

plotting partial deriviatives
Dear R Helpers: I am trying to annotate a plot. The following code snippet works, but it is kind of a kludge since it adds the partial derivative symbols after creating the plotmath frac(). Is there a more elegant way to write a partial derivative? dev.off() plot(NA, xlim=c(-3,3), ylim=c(0,1.6), xlab="", ylab="", tck=-0.015) text(1.6, 1, expression(paste("slope =

[PATCH v2 1/1] xen/netback: correctly calculate required slots of skb.
When counting required slots for skb, netback directly uses DIV_ROUND_UP to get slots required by header data. This is wrong when offset in the page of header data is not zero, and is also inconsistent with following calculation for required slot in netbk_gop_skb. In netbk_gop_skb, required slots are calculated based on offset and len in page of header data. It is possible that required slots

Scripting - sort of
Dear R-ians: I'm running R2.9.2 on a 6 year old Windows XP DELL with 2 Gig RAM and a 3MHz Pentium 4 chip. I've written a package using the User Menus Under Windows commands (winMenuAdd, etc). It works very well. I have 6 test cases and running any one of them requires many selections form the menus and some keyboard entry, and it takes me hours to exercise them all to see

programming advice?
Dear R-helpers: I am doing some exploratory programming and am considering a routine that has several other routines defined within it, so that I can avoid a large and messy global re-programming to avoid naming conflicts. My question is this: Because it is interpreted, does R have to re-build these internal routines every time the new routine is called? I'm not overly worried right now

help with R semantics
Greetings: I'm running R2.6.2 on a WinXP DELL box with 2 gig RAM. I have created a new glm link function to be used with family = binomial. The function works (although any suggested improvements would be welcome), logit.FC <- function(POD.floor = 0, POD.ceiling =1) { if (POD.floor < 0 | POD.floor > 1) stop ("POD.floor must be between zero and one.") if

clear screen?
I?ve been using this routine for several years. I?m sorry, I don?t remember where I got it. It works as it should, viz. it blanks the R console. But it requires package rcom and now that requires rscproxy. cls <- function () { require(rcom) wsh <- comCreateObject("Wscript.Shell") comInvoke(wsh, "SendKeys", "\f") invisible(wsh) } > cls()

R-2.4.0 and MS Vista OS - installing packages
I have installed Microsoft Vista Release Candidate 1, and R-2.4.0, on a 4 year old DELL box with a 2.26 GHz P4 and 1 gig. It was a clean install ? R is the only non-MS program running.

screen resolution effects on graphics
Greetings, R-Citizens: I have the good fortune of working with a 19" 1280 X 1024 pixel monitor. My R-code produces nice-looking graphics on this machine but the same code results in crowded plots on an older machine with 800 X 600 resolution. In hindsight this seems obvious, but I didn't anticipate it. My code will be used on machines with varying graphics (and memory) capacity. Is

compiled help pages
Greetings: This should be easy but it isn't. I have a home-brew package that works fine, with compiled html help pages, all 150 of them. I want to make a similar package but not from scratch since only a half-dozen routines are changed. So I created a new directory, copied the old package into it and changed the name to newSTUFF. I changed the names of all help pages too, as weill
