[R] Merge: how can I keep discarded values?

Good morning, I am merging two datasets and I would like to save the non-matching rows in a separate file. The problem is how to retrieve the non-matching rows in R. Example: DATASET A code nomi A1 Franco A2 Mario A3 Andrea A4 Sandro A5 Luca DATASET B codeboo

Somebody will come up with a more elagant solution, but a quick fix would be: plot(df$Y[df$pch_type != "21"],df$X[df$pch_type != "21"], pch=df$pch_type[df$pch_type != "21"]) points(df$Y[df$pch_type == "21"],df$X[df$pch_type == "21"],pch= 21) Marc Bernard wrote: > Dear All, > > I have a

[R] Discriminant Analysis- Apparent error rate

R-help, I'm trying to evaluate the misclasification rate of an estimated discrimated function (hyDA) hyDA <- with(hyB, lda(Maturity ~ Length + Weight)) , so here is what I do (code from S-plus 6.1 Guide to Statistics Vol. 2 p 101) test <- predict(hyDA) tbl <- table(hyB$Maturity, test$class)

Re: [R] Can I set the proxy server and authentification from within R?

Thanks a lot for your help! One more remark if somebody runs into the same problem: The .Renviron file has to be in the correct directory. It can be checked with Sys.getenv('http_proxy') that the settings have been actually read in. The ".Renviron" file looks like this now: http_proxy=http://pro

Re: [R] [Rd] How to link to vignette from .Rd file

Thanks for the tip. Actually I found that I can just write vignette("vignettename") in a demo. I think that's the easiest way to link to a .pdf file. It works only if the .pdf file is built from a Sweave file. I thought that I could just put a .pdf file and an index.html in inst/doc/ but I get

I think you need the following: attach(DAT.nr) plot(jd.s, jd.h, type = "n") text(jd.s, jd.h, t_no) I hope it works. Best, Dimitris - Original Message - From: "CG Pettersson" <[EMAIL PROTECTED]> To: "Dimitris Rizopoulos" <[EMAIL PROTECTED]> Cc: "CG Pettersson" <[EMAIL PROTECTED]>;

Re: [R] Plotting symbols with two positions?

Dear Dimitris, Thanks a lot, but I didn't really manage to apply it in my context, I first got an error message and then an ugly plot. I have also got the advice from Gabor Grothendieck to use letters instead of numbers, but I do prefer numbers as this is the normal way of referring to the indivi
