Dear Rexperts: (R 2.0.1 on Windows XP Pro) Is the following problem unique to my setup? If it's a known problem, I didn't see it at http://bugs.r-project.org/ nor find discussion in the archives. plot(1:10) loc <- c(5, 6) text(loc, labels = "a") Produces expected results according to ?xy.coords. plot(1:10) loc <- list(x = 5, y = 6) text(loc, labels = "a") No

Hi ReXperts, I have a file 'XFile' that I wish to append to the end of file1, file2, file3, file4, and file 5. Can't figure out how to set up the loop. Please help.

Dear Rexperts, I am trying to add a '+' identifying the mean in a boxplot using the following sizelist <- split(size, grp) centers <- boxplot(sizelist, style.bxp = "att", medpch = "o", ylab = "Prostate Volume (cm3)") points(centers, unlist(lapply(sizelist, mean)), pch = "+") But, I get error Error in xy.coords(x, y) :

Hi, I am working with the RCurl package and I am using the curlPerform function for an soap-query. The problem is that the code is usually working well, but sometimes the connection gets lost. So I wrote a while-loop to repeat the query if anything might happened so that the same query runs again, but if the query-faults it takes a very long time for the repetition. My question is if there

Dear Rexperts, I have recently build R-2.3.0 from source on a Linux system and have encountered the following problem (perhaps not exactly a problem, but a minor display flaw): > demo() +------------here is how the output looks in less------------+ Demos in package <E2><80><98>base<E2><80><99>: is.things Explore some properties of R

Dear Rexperts, after building R 2.4.0 from source in a temporary directory (*without* installation), and subsequently moving the whole source/build tree to another location, I have noticed that I had to change the variables R_SHARE_DIR, R_INCLUDE_DIR, and R_DOC_DIR in the wrapper-script /lib/R/bin/R as to reflect the current situation. However, when I try to run the HTML help via

Dear Rexperts, I intend to burn some R CDs to colleagues in Vietnam. I want to put all binary files for base as well as contributed packages (for both Windows and Linux). It is very time consuming if I download files by files. Is there a place a can buy a CD with all the mentioned files?

Dear Rexperts, First of all let me say that R is a wonderful and useful piece of software. The only thing is that sometimes it takes me a long time to find out how something can be done, especially when aiming to write compact (and efficient) code. For instance, I have the following function (very rudimentary) which takes a (very specific) data frame as input and for certain subsets

Hi! I've performed a Google Scholar Search using a query, let's say "Frank Harrell", and parsed the links to the EndNote references from the resulting HTML code. Now I'd like to download all the references automatically. For this, I have tried to use RCurl, but I can't seem to get it working: I always get error code "403 Forbidden" from the web server.

Dear ReXperts, I have the below text file output. I need to extract the T, QC, QO, QO-QC and WT columns for the data between T = 10 and T=150. Any ideas?

When I click an InPlaceEditor field in Firefox 1.0.7, the page scrolls up to the top. That''s disconcerting, and often ends up with the editable field out of the viewable pane. I can duplicate this on both Mac and PC. Is there a way to prevent this? Even the demo at http://wiki.script.aculo.us/scriptaculous/show/Ajax.InPlaceEditor does this. Jay Levitt

Dear Rexperts, lately I'm having troubles installing the rgl package via install.packages("rgl", dependencies=T) in the R 2.4.0 backport running under Ubuntu 6.06 LTS. I get the following error messages, despite having installed libx11-dev (as recommended in a similar post about SUSE 10.1): trying URL 'http://cran.xedio.de/src/contrib/rgl_0.68.tar.gz' Content type

Hello, Some code using RGoogleDocs, which had been working smoothly since the summer, just stopped working. I know that it worked on November 3rd, but it doesn't work today. I've confirmed that the login and password still work when I log in manually. I've confirmed that the URL gives the same error when I paste it into Firefox. I don't know enough about this web service to figure

Hi everybody, I think that I am missing something fundamental in how strings are passed from a postForm() call in R to the curl or libcurl functions underneath. For example, I can do the following using curl from the command line: $ curl -d "Archbishop Huxley" "http://www.datasciencetoolkit.org/text2people"
