Dear useRs, upon request, the VGAM package (currently version 0.7-1) has been officially released on CRAN (the package has been at my website http://www.stat.auckland.ac.nz/~yee/VGAM for a number of years now). VGAM implements a general framework for several classes of regression models using iteratively reweighted least squares (IRLS). The key ideas are Fisher scoring, generalized linear and additive models, IRLS and vector smoothing. It is a large R package that fits ma...

Dear all, How can I get the duplicated elements from a vector? For example, x <- c("yes", "no", "yes", "yes", "no", "not sure"), how can I filter out all the elements which occured >=2 times? Thanks for any help! Regards, Leon

...le the WxDialog class. OnXXX are non-virtual in WxWidgets, but virtual in wxruby-swig ShowModal are virtual in WxWidgets, but non-virtual in wxruby-swig I realize that wxruby-swig is in a very highly experimental stage, but would appreciate it if someone can shed some light here.

...rwards. For the glm(), the data frame d.AD is constructed but not used. Also, its 3 components were assigned first in the general workspace, so they float around dangerously afterwards like in the lm() example. Rather than attached improved .Rd files here, they are put at www.stat.auckland.ac.nz/~yee/Rdfiles You are welcome to use them! Best, Thomas

Dear all, I have a data frame with several columns, and I have the specified order of a given column. How can I re-order the rows of my data frame accroding to this specified order? for example, x = data.frame( num = 1:26, alpha = letters[1:26], stringsAsFactors=FALSE) z = sample(x$alpha, replace=FALSE) Can I re-order x accroding to z ?

In the following code, I'd like to be able to create a new variable containing the value of the names of the list. a <- data.frame(var.1 = 1:5) b <- data.frame(var.1 = 11:15) test.list <- list(a=a, b=b) # in this case, names(test.list) is "a" and "b" # and I'd like to use lapply() so that # I get something that looks like # var.1 var.2 # 1 a # 2

I'm interested in testing whether or not a character string is numeric or not as follows: is.na(as.numeric('3')) # returns F is.na(as.numeric('A')) # I'd like this to return T without issuing a warning about NAs introduced by coercion. I guess you could suppress the warning with options(warn=-1), but I was wondering if there's an alternative. Or perhaps an

Hi, In R I get the following: > x <- 1:9 > f <- as.factor(1:9) > i <- model.matrix(~x+f) > > attr(i, "assign") [1] 0 1 2 2 2 2 2 2 2 2 whereas in S I get the following: > attr(i, "assign") $"(Intercept)": [1] 1 $x: [1] 2 $f: [1] 3 4 5 6 7 8 9 10 Has anybody written a model.matrix function to get the same result as S?

...it is possible to view the Fortran source code called by R functions. In particular, I am interested in the "leaps.setup" function in a package called "leaps", which calls Fortran functions "ssleaps", "initr" etc. Any help would be greatly appreciated.

dear all, I would like to know whether survdiff and survReg function in the survival package work for left-truncated and right-censored data. If not, what other functions can i use to make comparison between two survival curves with LTRC data. thanks for any help given sing yee

Dear all, I have a question about "union". "union" handles two vectors' elements to get their union, but I have many vectors and I want to get the union of all of them. So I wrote a loop: all <-c(); for(var in ls(pattern="xyz")) # all of the vectors with pattern of "xyz" { all <- union(all, var); } but the result is like this:

A naive question: what happened to the xlsReadWrite package? http://cran.r-project.org/web/packages/xlsReadWrite/ It says that it was removed from the CRAN repository. Are there any plans for it be available again? Thanks, Andrew [[alternative HTML version deleted]]

Take the following code: foo <- list() foo[[1]] <- list(a=1, b=2) foo[[2]] <- list(a=11, b=22) foo[[3]] <- list(a=111, b=222) result <- do.call(rbind, foo) result[,'a'] In this case, result[,'a'] shows a list. Is there a more elegant way such that result is a "regular" matrix of vectors? I imagine there are manual ways of going about this, but I was

This is kind of a dumb question: I know you can use isdebugged() to find out if a specific function is flagged for debugging, but is there a way to list all the functions that are flagged for debugging? Thanks, Andrew [[alternative HTML version deleted]]

...have thought about this before already, any specific problems?), or continue with the template generator in the current wxruby-4.0. The RUBY port of the SWIG seemed to be developed by the author of FXRUBY, guess it might be good to communicate with the FXRUBY camp as well, then. Cheers, Phuah Yee Keat

I've been trying to figure out a parameter that will let you separately adjust the parameters for the axis line from the tick mark. In the following example, I would like to suppress the axis line, but keep the tick marks. Thanks, Andrew foo <- data.frame(x=1:3, y=4:6) plot(foo$x, foo$y, type="n", axes=F) points(foo$x, foo$y) axis(side=1, at=foo$x, lty=0) #would like to figure

I've searched for the answer to this in the help list archive, but wasn't able to get the answer to work. I'm interested in converting a row of a data.frame into a vector. However, when I use as.vector(x,[1,]) I get another data.frame, instead of a vector. (On the other hand, when I use as.vector(x,[,1]), I get a vector.)
