Greetings: I've searched the R archives with no luck. I want to print this to the screen as part of on-screen instructions as an example: default.FACTOR.labels <- c("Probe1", "Probe2", "Probe3") I can't seem to trick gsub() gsub("'", "\"", "default.FACTOR.labels <- c('Probe1', 'Probe2',

Can someone show me some code to do normalization by the median of some control genes for the example below? Many Many Thanks in advance This strategy selects a subset of genes (called ?control genes?) and makes the median of their data distribution similar across arrays. ??? ??? id1??? id2??? id3 control1??? 0.8??? 0.7??? 0.6 control2??? 0.6??? 0.2??? 0.4 probe1??? ??? 0.3??? 0.2??? 0.5

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, 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: 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: 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

Greetings R-Helpers: I am trying to help a Chinese colleague who is experiencing difficulty loading my package. He is running WindowsXP and the Chinese version of R2.8.1. As you can see from his screen-copy (below), my package is successfully unpacked but cannot be loaded because splines balks when attempted to be loaded. Package mh1823 requires package survival, which in turn requires

Greetings, R-Helpers: I am trying to build a package on WinXP, something that I have done before, but infrequently, and have recently updated both the Rtools and the version of R being used. My test case fails after successfully creating the compiled html files with this error message: . . . Created c:\DOCUME~1\CHARLE~1\LOCALS~1\Temp\Rbuild142865646\March18\chm\March18.chm, 41,494

Greetings, R-ians: I am sure I am missing something obvious. How do I provide a CITATION file for my home-brew package, so that it will be packaged using R CMD build --binary myPackage? I have placed a CITATION file in the myPackage directory along with the DESCRIPTION file, but it is ignored. Thanks for your guidance. Charles Annis, P.E. Charles.Annis at StatisticalEngineering.com

Dear R-Helpers: I'm running R version 2.8.1 on a 1 year old HP Pavilion with a AMD Athelon 64 Dual Core Processor 4800+ 2.50GHz chip, Vista Home Premium SP1, and 2 GB RAM. I can't add packages (even running as Administrator) because I can't connect to a CRAN mirror. > chooseCRANmirror() (After nearly a minute I see the menu, and after any selection I immediately see) Warning

I have a vector, (not a list) > repeated.measures.FACTOR.names [1] "Insp1" "Insp2" "Insp3" "Insp4" "Insp5" "Insp6" "Insp7" "Insp8" "Insp9" and would like to convert this into a single string "Insp1,Insp2,Insp3,Insp4,Insp5,Insp6,Insp7,Insp8,Insp9" I can do that with a loop, but isn't there

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-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.

Greetings: I would like to use tcl/tk with R, and have read "A Primer on the R-Tcl/Tk Package" by Peter Dalgaard in Rnews, Volume 1/3, September 2001. Are there more recent do-it-yourself instructions available? I have been unsuccessful with the example in the tcltk2 package due to a syntax error. I think that I have isolated the problem to this code snippet: for (i in

Friends: I am a long-time R user, learning tcl/tk, and am tying myself in knots over something that should be simple. I want to create a frame and put that frame inside the toplevel frame. This works (i.e. it places text in col 1, and the corresponding entry box in column 2) and later frame.2 resides where it should in the toplevel frame. tkgrid(tklabel(frame.2, text="FACTOR column

Friends: I have a tcltk widget for inputting constants and other values that are needed by subsequent R functions. My widget works well. I have an OnOK function that does what I had hoped it would. Among other input items the widget also uses 6 radio buttons to select one of 6 choices. It functions as it should. Here is the problem: I would like one of the buttons to be the default and to

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

Greetings: I wish to use a tcl/tk widget to ask for user-selected parameter values. My widget works ? it asks for and returns to my workspace the stuff I need. Here is a snippet of my code: ############################### OnOK <- function() { LOG.X <<- as.logical(as.character(tclvalue(log.X.buttonValue))) LOG.Y <<- as.logical(as.character(tclvalue(log.Y.buttonValue)))

Dear R-helpers: It seems that I have a mental block. (Some say that it sits atop my shoulders.) For reasons too tedious to retell I have an R object: > input.line[7] [1] "-13.24, -11.24, -9.24, -7.24, -5.24, -3.24, -1.24, 0.76, 2.76, 4.76, 6.76, 8.76, 10.76, 12.76, 14.76, 16.76, 18.76, 20.76, 22.76, 24.76, 26.76, 28.76, 30.76, 32.76, 34.76, 36.76, 38.76, 40.76, 42.76, 44.76, "
