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...

Dear Rexperts, I am using R to query google. I am getting different results (in size) for manual queries and queries sent through "getForm" of RCurl. It seems that RCurl limits the size of the text retrieved (the maximum I could get is around 32 k bits). Any idea how to get around this ? Thanks in...

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 r...

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 rudiment...

First, many thanks to Frank Harrell for once again helping me out. This actually relates to the next point, which is my contribution to the 'why don't social scientists use R' discussion. I am a hybrid social scientist(child psychiatrist) who trained on SPSS. Many of my difficulties in coming to terms with R have been to do with trying to apply the logic underlying SPSS, with dire
