I'm attempting to pass a string argument into the function randomForest but I get an error: state <- paste(list("fruit ~", "apples+oranges+blueberries", "data=fruits.data, mtry=2, do.trace=100, na.action=na.omit, keep.forest=TRUE"), sep= " ", collapse="") model.rf <- randomForest(state) Error in if (n==0) stop ("data(x) has 0 rows") argument is of length zero. -Thanks in advance,

You''ll need to install the ''openid'' gem for this, and require it in your camping app: class Login < R ''/login'' def get this_url = ''http:'' + URL(''/login'').to_s unless input.finish.to_s == ''1'' # start doing the auth here begin

It has been annoying me for a while that data in user areas are more difficult to handle than those in the packages. Especially for beginners, it would be very handy to be able just to say "data(mydata)", rather than "mydata<-read.table('mydata.txt',header=T)" What just occurred to me was that the following hack actually works: Type

I've just gotten through translating my notes for the course in basic statistics for health researchers. I've placed a copy on ftp://blueberry.kubism.ku.dk/priv/R-intro.tgz This is essentially a translation of the Danish notes that I wrote during the Autumn of 1997 for use with Rsept, i.e. roughly R v.50. They lean heavily on the textbook, Altman: Practical Statistics for Medical

[Not important for message below; in this moment link from CRAN to the 'R Bug Tracking system (http://blueberry.kubism.ku.dk/R)' is down (at least, I get a "The requested URL /R was not found on this server." message)] To display properly this message, you mailer must handle properly latin1 encoding. With other encoding, I suppose that the role played by 'y

Is there some way run an R script from the command line? Can I put a line at the top of the file like I would for a bash or perl script? For example, a such a script (test.r) might look like. #!/usr/bin/R x <- c(1:10) print(x) running ./test.r at the command line doesn't work. So is there a way to do this? Am I missing something, or do I just have to start R and source() the

Hey Judofyr! Fix this! When someone sets a cookie using @cookies.something = ''data'' it should be set with the path going to the camping app''s root, not with no path, otherwise only that controller with the same parameters will ever see the cookie again! Please change this code: > @cookies.each do |k, v| > @response.set_cookie(k, v) if o[k] != v > end

It is quite tempting to start simple data entry sessions where you need to type in the data like this: my.frame<-data.frame(a=numeric(0),b=numeric(0)) fix(my.frame) (and if factors are involved, that is pretty much what you'd have to do in order to get the appropriate levels) However, in the X version, this seems to cause the data editor to freeze as soon as one hits Enter after

Hello, I tried to do a 'sem' analysis for data of how blueberry consumption by birds is influenced by a pollution gradient, using distance and vegetation structural and composition variables, but I got the following error message: Error in sem.default(ram = ram, S = S, N = N, param.names = pars, var.names = vars, : S must be a square triangular or symmetric matrix This may be very

I am occasional getting "Segmentation Fault - core dumped" in R 0.62.3 (I think more often then I did in 0.62.2). I have not been able to do this in any reliably reproducible way yet, but thought I would mention the problem in case some else can isolate it.

I've rolled up R-1.5.1.tgz a short while ago. This is a patch upgrade, fixing the most important bugs that cropped up after the 1.5.0 release. A set of recommended packages which have been tested with R-1.5.1 has been bundled up. Binary distributions should include these packages. You can get the files from the developer site ftp://cvs.r-project.org/pub/CRAN/src/base/R-1.5.1.tgz

I've rolled up R-0.65.1.tgz a moment ago. As usual, you shouldn't get it from Auckland, but wait for it to be mirrored at a CRAN site near you within a day or two. For those who are too curious to wait, I'll put a copy in ftp://blueberry.kubism.ku.dk/pub/R-devel/R-0.65.1.tgz There's also a version split in two for floppies and a patch file if you prefer that. (If you use the

I am trying to translate code from S-PLUS to R and R really struggles! After starting R with the foll. R --vsize 50M --nsize 6M --no-restore on a 400 MHz Pentium with 192 MB of memory running Linux (RH 6.2), I run a function that essentially picks up an external dataset with 2121 rows and 30 columns and builds a lm() object and also runs step() ... the step() takes forever to run...(takes very

Okay, I decided to go with Magnus'' :halt idea. I was skeptical, but good points from the blueberry australian. Anyway, it was only like a thirteen-byte patch. Now THAT''S a camping patch! _why
