similar to: Install Packages in Windows Vista

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. I cannot install packages from CRAN, nor from local zipped files. (I have R-2.4.0 installed on a Windows XP machine and have had no problems so the difficulty seems to be Vista not R, however they aren't

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

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,

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

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.

Did anyone try to run R under Window Vista, especially Windows Vista 64bit? Thanks.

Hi, Windows Vista includes additional security mechanisms (User Access Control) whose defaults make it difficult to install or update R packages. To avoid these problems you need to go to Computer-> Program Files Right click on the R directory and select "properties". Now select the security tab. Give your user ( which is the use R whose priviledges R runs under) Full Control to the

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

Hi, I have a new computer with Windows Vista and I am trying to use RWinEdt, which I have always used. I am using R version 2.5. The installation of the RWinEdt library is funny. First, it didn't install at all. Then, I uninstalled/reinstalled both R and WinEdt, downloaded the package again from the CRAN repositary, got some error messages, but RWinEdt initialized. I closed R and WinEdt,

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 =

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,

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

Greetings, Amigos: I have been trying without success to convert a character string, > repeated.measures.columns [1] "3,6,10" into c(3,6,10) for subsequent use. as.numeric(repeated.measures.columns) doesn't work (likely because of the commas) [1] NA Warning message: NAs introduced by coercion I've tried many things including strsplit(repeated.measures.columns, split =

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

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()

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

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

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
