Dear R users, Two questions: 1) Is there a way to simplify the mtext() line below ? beta=c(1,-1) m=5 plot(1) mtext( bquote(paste( beta == .(paste( "(", paste(beta, collapse=", "), ")" )) )), outer=TRUE,line=-3) 2) How do I get the embedded carriage return "\n" below to work, i.e for the text that follows it to appear on the next line? beta=c(1,-1) m=5

Dear R list, I've read the function writing sections on both "An introduction to R" and "R language Definition" manuals but still don't understand why the following gives an error message: fun <- function(x, ...) x + y fun(1, y=2) I get: Error in fun(1, y = 2) : object "y" not found I'd appreciate any help in understanding this. R version 2.4.1

Dear R helpers, I have a data frame where missing values for numeric variables are coded as 999. I want to recode those as NAs. The following only partially succeeds because numeric variables are converted to character in the process: df <- data.frame(a=c(999,1,999,2), b=LETTERS[1:4]) is.na(df[2,1]) <- TRUE df a b 1 999 A 2 NA B 3 999 C 4 2 D is.numeric(df$a) [1] TRUE

I've searched the archives and read the xyplot help but can't figure out the 2 lattice questions below? Consider: library(lattice) DF <- data.frame(x=rnorm(20), y=rnorm(20), g1=rep(letters[1:2], 10), g2=rep(LETTERS[1:2], each=10), g3=rep(rep(letters[3:4],each=5),2)) xyplot(y ~ x | g1 + g2, groups=g3, data=DF) 1) Is there a way to get one strip per row and column

I'm trying to: Resample with replacement pairs of distinct rows from a 120 x 65,000 matrix H of 0's and 1's. For each resampled pair sum the resulting 2 x 65,000 matrix by column: 0 1 0 1 ... + 0 0 1 1 ... _______ = 0 1 1 2 ... For each column accumulate the number of 0's, 1's and 2's over the resamples to obtain a 3 x 65,000 matrix G. For those

I need to read two different random lines at a time from a large ASCII file (120 x 296976) containing space delimited 0-1 entries. The following code does the job and it's reasonable fast for my needs: lineNumber = sample(120, 2) line1 = scan(filename, what = "integer", skip=lineNumber[1]-1, nlines=1) line2 = scan(filename, what = "integer",

Dear all, Further to my previous message I now made a one-line convencience function to export your currently active graphics window/plot to either Word or Powerpoint in Office-native vector-based DrawingML format using either export2ppt(file="plot.pptx") or export2doc(file="plot.docx") : see

Dear R users, Consider the following example function: f = function(a,b) { g = function(x) a*x + b h = function(x) g(x)^2 + x^2 opt = optimize(h,lower = -1, upper = 1) x.min = opt$minimum h.xmin = opt$objective g.xmin = g(x.min) return(c(x.min, h.xmin, g.xmin)) } In my real problem the function that plays the role of "g" is costly to compute. Now, to

I cannot seem to find any reference to labels in realtime extensions - using 1.4. I've googled until my eyes have bled, and also scoured voip-info.org. Is there anything that helps me here ? Many thanks. Julian

Currently, when CIFS users create files these get "Domain Users" as their group. I would appreciate a different group in general and yet another group for some selected users. Googling until my fingers bled I learned that this group is somehow magically encoded in the RID 513 set as primaryGroupID for all users. With Samba3 there used to be commands like 'net groupmap' to

Hi there, I'm sure this must have been discussed before, but I can't find anything that addresses exactly my problem in the archives. The problem I ran into is, that a samba-share relying on POSIX file-permissions stops working as soon as the shared folder is a NFS-mount itself. In that case, it is no longer possible for any user to access files or folders. So in my example, if

Hello, I'm doing some graphics for a paper and a need customize such with filled region above the density curve. My attempts I get something very near what I need, but I don't solve the problem of use semitransparent filled. Below a minimal reproducible code. Someone has any idea? require(lattice) # toy data... dt <- expand.grid(A=1:2, B=1:3, y=1:50) dt$y <- rnorm(nrow(dt), dt$B,

I am interested in finding an R version of SAS "Proc Varclus". SAS's Proc Varclus implements an oblique cluster analysis based on principal components. How can I find out if R has a package that runs the same algorithm implemented in SAS "Proc Varclus"? Thank you, Mary Helen Black __________________________ Mary Helen Black, M.S.

Hello I have been having problems with authentication on a suse 9 box with samba 3.0.3 installed from rpms. I have googled till my fingers bled, there is just the question, no answer, someone must have been able to solve it out of all the people who had the problem? I joined the domain with net join, this was successful I can list users/groups, authenticate and check the secret with wbinfo

Hello everybody, I would like to solve the problem described below in R (if possible). I am very new to R and have therefore no idea what to even look for in the docu. Therefore, if someone could tell me if this is possible in R and where I might find the respective docu then I would already be very thankful. I have a large set (a few million) of points in 3D. I would like to create a

Dear R devel, being constrained to a windows environment at work and having colleagues being accustomed to the Microsoft Office Suite, I was looking for a way to have the RweaveLatex driver for Sweave automatically generating 'win.metafile's in addition to the pdf graphics. Without this functionalilty, the generation of emf-graphics is quite laborious, I think: <<>>= plotit

I use R to create .eps graphics and then use oodraw to convert them to .emf versions. (One reason I do this is that OOo tends to re-size .eps files and I haven't found a way to stop it or change it once the graph is resized. .emf files are not distorted by OOo - fortunately.) I use a command like: > oodraw filename.eps & The gui opens and then I select .emf and do an export. I

syskern (`Functions for writing code that is OS and R/S independent', an amazing description given the reality) fails Rcmd check on Windows, and also gives incorrect information where it does work. There are already correct OS-independent functions for these purposes in R. It appears not to be needed to run the other three packages in the dse bundle, but to be the only R package that

Dear R-listers, I have created a plot to display the density lines for the same variable by different entities. Now, I want to fill the area under the density lines with semitransparent colors. Though I have checked that in web-searching and book-reading, I still do not perform that. Could anyone please give me any helps or advice? Thank you in advance. The data and code I used listed below: #
