Dear All, to my surprise as.factor does not accept a levels argument. Maybe I did not read the documentation well enough. See the example below. I wanted to use ch1 as factor in the newdata argument of survfit, so I assumed that I could write as.factor(ch1, levels=ch1), since the order should be kept. But as.factor(ch1, levels=ch1) results in the error: Error in as.factor(ch1, levels = ch1)

Dear All, since years I am struggling with Surv objects in data.frames. The following seems to have to do with it. See below the modified example from the help page of survSplit. The original works, as expected. If, however, a Surv object is added to the data.frame, each record gets doubled. Is there some solution other than avoiding Surv objects in data.frames? Thanks, Heinz

Dear All The "R CMD check" on the "zoo" (1.7-11) package results in an error on my environment. It can be reduced to the following example: ---------------------------------------------------- > require(zoo) > read.zoo(system.file("doc", "demo1.txt", package = "zoo"), sep = "|", format="%d %b %Y") Error in

Hi all, I believe there is an issue with passing NULL to the function I(). class(NULL) # "NULL" (as expected) print(NULL) # NULL (as expected) is.null(NULL) # TRUE (as expected) According to the documentation I() should return a copy of its input with class "AsIs" preprended: class(I(NULL)) # "AsIs" (as expected) print(I(NULL)) # list() (not expected!

Dear All, reposting, because I did not find a solution, maybe someone could check the example below. It's taken from the help page of survdiff. Executing it, gives the error "Error in floor(temp) : Non-numeric argument to mathematical function" best regards, Heinz library(survival) ## Example from help page of survdiff ## Expected survival for heart transplant patients based

Dear all, Using the SetInternet2(TRUE) option works wonders with R in my sealed down work-environment. However, I'd like to use RCurl and apparently the proxy settings are not carried over. Is it possible to figure out the proxy-IP and port number from R after invoking SetInternet2? //M

Hi all, The documentation for head() and tail() describes the behavior of these generic functions when n is strictly positive (n > 0) and strictly negative (n < 0). How these functions work when given a zero value is not defined. Both GNU command-line utilities head and tail behave differently with +0 and -0: http://man7.org/linux/man-pages/man1/head.1.html

In addition, signed zeroes only exist for floating point numbers - the bit patterns for as.integer(0) and as.integer(-0) are identical.

In response to an earlier discussion about finding the fastest/best/nearest CRAN site, I geocoded (using my geonames package) the locations of the CRAN sites returned by getCRANmirrors. I've mapped them here: http://www.maths.lancs.ac.uk/~rowlings/R/Cranography/ The geocoding may have got it wrong, so if CRAN site maintainers want to send me a real lat-long (in WGS 84 aka EPSG:4326) I'll

Hi, I run a script file by dropping it on a windows batch file that runs R in --slave modus. In a subfunction there is the call to file.choose(). The problem is, that the dialog does show only folders but no files at all. It's quite strange: a) without --slave modus the files are shown, b) when I copy the whole script file in a different file it was also ok, but when I renamed the script, the

When executing 'dyn.load("this/dll/does/not/exist.dll")' the resulting error message is scrambled. Not all characters will be displayed and when I select the empty region text disappears/reappears.
