Hi all, I have a problem to estimate Std. Error and t-value by ?polr? in library Mass. They result from the summary of a polr object. I can obtain them working in the R environment with the following statements: temp <- polr(formula = formula1, data = data1) coeff <- summary(temp), but when the above statements are enclosed in a function, summary reports the following error:

Hi all, I'm plotting to get the intersection value of three curves. Defining the x-axis as dsm, the following code works; dsm = c(800,600,NA,525,NA,450,400,NA,NA,NA,0) s3 = seq(0.05,1.05,0.1) plot(dsm,s3,col="blue",las=1,ylab="fraction",xlab="distance (km)") fc <- function(x,a,b){a*exp(-b*x)} fm <- nls(s3~fc(dsm,a,b),start=c(a=1,b=0)) co <- coef(fm)

Hi I want to draw a rectangle behind a barplot such that it highlights those particular bars from the rest of the plot. I have figured out how to draw a barplot(), and then how to draw a rectangle of the correct shape and size (using rect()), but when I use rect() it draws over the top of the bars, and then when I re-draw the bars, it draws with a white background, thus eliminating my rectangle!

Hello List I'm moving this over from the bioC list as, although the problem I'm working on is biological, the current bottle neck is my poor understanding of R. I wonder if someone would help me with the following function. cumulMetric <- function(deMirPresGenes, deMirs){ ??? #need to match position of each miR in deMirPresGenes with its FC to form a vector of FC in correct order ?

Hi all, I'm trying to get the value of y when x=203 by using the intersect of three curves. The horizontal curve does not meet with the other two. How can I rectify the code below? Thanks Muhammad ts <- 1:10 dd <- 10:1 ts <- seq(200,209,1) dd <- c(NA,NA,NA,NA,1.87,1.83,1.86,NA,1.95,1.96) plot(ts,dd,ylim=c(1.5,2)) abline(lm(dd~ts),col="blue",lty=2)

Source versions would only have been available with a nondisclosure agreement, and relatively few copies would have been distributed in source.

After upgrading my small test system from Debian Etch->Lenny via a complete reinstall, I find my g729 hostid has changed. Same machine, same CPU, same NIC! It doesn't seem reasonable that I have to burn my one "no-hassle" re-registration for a simple OS upgrade. The README only says that hostid is based on MAC addresses of all NICs, but that doesn't seem to be true. Does

Dear All I am trying to convert from the type "expression" to the type "numeric". The following works: > x <- expression(6.2) > as.numeric(as.character(x)) [1] 6.2 However, the following does not work: > x <- expression(62/100) > as.numeric(as.character(x)) [1] NA Warning message: NAs introduced by coercion Any idea about how to deal with the second case?

A colleague is receiving some data from another person. That person reads the data in SAS and it takes 30s and uses 64k RAM. That person then tries to read the data in R and it takes 10 minutes and uses a gigabyte of RAM. Person then goes on to say: It's not that I think SAS is such great software, it's not. But I really hate badly designed software. R is designed by

Dear all, in the coming Winter Semester, I will be a teaching assistant for a course in Survival Analysis. My job will be to do the lab sessions. The software used for these lab sessions will be R. Most of the students have a background in social sciences and the only stats package they used so far is most likely SPSS. So I assume they might be quite surprised the first time they see R

Hi all, I am trying to run some plots on data, but when loading he CSV data file R is stopping and I am getting an out of memory error. Anyway to tweak this somehow to get it to run? Using WinXP with 4 GB RAM Tnx Bruce

I don't think anyone denies that you *could* make an EXE to do all that. The discussion is on *how easy* it should be to create a single file that contains an initial "main" function plus a set of bundled code (potentially as a package) and which when run will install its package code (which is contained in itself, its not in a repo), install dependencies, and run the main()

If you index a vector with a vector that has NA in it, you get NA back: > x=101:107 > x[c(NA,4,NA)] [1] NA 104 NA > x[c(4,NA)] [1] 104 NA All well and good. ?"[" says, under NAs in indexing: When extracting, a numerical, logical or character ?NA? index picks an unknown element and so returns ?NA? in the corresponding element of a logical, integer,

A little while ago here we had a short discussion about Task Views - I think ignited by someone saying 'how many times do I have to say "have you read the Optimisation Task View?"?' and I poured some fuel on that fire by saying "Task Views" was a stupid name. Anyway, I did say that Task Views were rather brilliant, but were let down by their hidden position on the R

I can set up an entry widget (thanks to an old post by Barry Rowlingson) that gets a password and exits when the user clicks on the "OK" button. Anyone have any clever ideas for returning/ destroying the window when the user types a carriage return/ENTER in the text window? I've messed around a little with validate, validatecommand, but don't see any obvious way to do it ...

In response to an earlier discussion about finding the fastest/best/nearest CRAN site, I geocoded (using my geonames package) the locations of the CRAN sites returned by getCRANmirrors. I've mapped them here: http://www.maths.lancs.ac.uk/~rowlings/R/Cranography/ The geocoding may have got it wrong, so if CRAN site maintainers want to send me a real lat-long (in WGS 84 aka EPSG:4326) I'll

I have just encountered the problem with rgl where plot3d figures don't interact with the mouse. My plots zoom in and out with the mouse wheel but the mouse buttons do nothing. I can't rotate the plot. This has been mentioned and discussed here and in other lists before, and the solution is to turn off Ubuntu's fancy graphics. Back in March, Ben Bolker said: """
