...ividual clusters and/or compare pairs of clusters in terms for the X-characteristics of their patients. Is anybody currently working on developing this sort of point-and-click capability in R? I would be very interested in becoming an alpha or beta tester of this functionality. ...BobO.

Hi Simon, I'm having trouble with nested parallel workers, specifically, forking inside socket connections. When mclapply is called inside a SOCK, PSOCK or FORK worker I get an error in unserialize(). cl <- makeCluster(1, "SOCK") fun = function(i) { library(parallel) mclapply(1:2, sqrt) } Failure occurs after multiple calls to clusterApply: > clusterApply(cl, 1,

Hi, S4 method dispatch can be very slow. Would it be reasonable to cache the most recent dispatch, anticipating the next invocation will be on the same type? This would be very helpful in loops. fun0 <- function(x) sapply(x, paste, collapse="+") fun1 <- function(x) { paste <- selectMethod(paste, class(x[[1]])) sapply(x, paste,

For example, I can perform almost all of the point-and-click operations I am interested in from existing menu items in JMP version 5.1, but I have not been able to develop usable JMP scripts to automate the basic processes. ...BobO.

Hi, Has anyone successfully used RCurl for posting data to a password-protected site? I have tired using option netrc=1 with both postForm and curlPerform (with postfields option) but can't authenticate. I would happily provide more details if some one has had some experience with this. Thanks very much. Valerie

Hi I'm working in the excellent ICEinfer package which calculates bootstrapped cost-effectiveness ratios Obenchain, B. (2011).

Hello, I am having trouble getting the curlPerform function to authenticate using the .netrc file. From the documentation I've read it certainly seems as though this function should be able to authenticate via the .netrc file. The example I am using here comes from the "R as a Web Client- the RCurl package" paper and demonstrates using the .netrc file to access the
