...explain how to reproduce the error. However, this would be time-consuming for anyone trying to do so. Sorry, I think I will just have to move to another distro, even Cygwin, for C development. That is a shame, because Centos is great in other respects. ----- Forwarded message from "John J. Boyer" <john.boyer at abilitiessoft.com> ----- Subject: Strange autotools error From: "John J.

My system is 5.6, with upgrades. I installed Java 6 from the Centos repository. It doesn't seem to have Java 7. I need the development package. How can I install Java 7 development safely?

...irst told about Mailman on this list. The problem is that Mailman keeps breaking. Right now, when I try to access the web interface I get an internal server error.

...ne would explain why the following example does not work: q <- function(y) {x + y}; w <- function(x){q(x)}; w(2); According to the discussion of Scope on page 46, it seems to me that R will interpret the free variable x in q as the parameter x in w, and so will give w(2) = 2+2.

Is there a function to efficiently search for a subsequence within a vector? For example, with x <- 1:100 I'd like to search for the sequence c(49,50,51), and be told that it occurs exactly once, starting at location 49. (The items in the vectors might be numeric or character, and there might be repetitions within the search pattern or within the vector I'm searching.) Duncan

Does anyone know if any R package has a function that will conduct Hollander's test of bivariate symmetry? (Hollander, Biometrika, 1971) Either the exact test or an asymptotic version would be sufficient for my purposes. Thanks.

Why doesn't this work? #Drop a variable name from a data frame DropLikeSAS <- function(x,df) { df[[x]] <- NULL 0 } DropLikeSAS("VarName", DataFrameName) Try it. The column VarName will not be deleted from the data frame DataFrameName. But x <-
