We've recently had a thread on beginners and FAQs and the like. I decided that it might be a good idea to offer a short list of on-line help pages that beginners should read. Goals: - the list short be short (I think mine is too long) - many of the commonest questions should find answers there (fairish) - I should have found the pages helpful myself (no question about that) - it's a beginning R topic list, not a beginning statistics topic list You can find my first draft at http://www.cs.otago.ac.nz/staffpriv/ok/R-help.txt I think something...

Remember that nchar() returns by default the number of *bytes* and not the number of characters. I've recently spotted many cases in which nchar() has been used with substr() which works in characters; this can lead to incorrect results. (This seems the commonest use of nchar() in packages.) There were two reasons why nchar() was left defaulting to bytes when we allowed MBCSs in R: 1) Many of the uses are of the form if(nchar(x)) or if(nchar(x)==0) or even if nchar(x) != 0. Computing the length of a string is an inefficient way to find out if it is n...

as my first project with *, i would like to replace our old neax2400(sds) with an * server. i've got an X100p and a TDM400 on hand already. for the CO lines, the X100p works ok with fxsks signaling though there are still strange things happening every now and again but more testing is on the way. my real big problem is the DID lines which our telcos call DDI lines; (incoming calls only) i

Hello dear R-help members, Very soon I am to give a lecture on R. And in that lecture I intend to move between: par(mfrow = c(1,1)) to par(mfrow = c(1,2)) back and forth. I anticipate this will damage the image proportions and will force me to resize the window. So far I have found it is possible to close the window and then reopen it (bigger/smaller) by using: dev.off()dev.new(width=5,

Hello all, I have read as many merge issues as I possibly could tonight and although I presume this is a small error, I have not found the solution to my problem. I'm trying to merge two data sets: dat0 and TransTable. As you can see below, dat0 has 8000 rows, whereas TransTable has 47296 rows. I would expect when I merge the two data sets, with all.x=F, and all.y=F, that the

Today I had a strange behavior that made me suspect of jQuery at first, but then it happened that I''ve faced two gotchas, one from CoffeeScript and one from Rails itself. I have something like this: routes.rb post ''/fields/:id.:format'' => ''fields#show'', as: :field, constraints: {id: /\d+/} post ''/fields/remove/:id''
