Hi everyone, My apologies if this isn?t the right place to submit this?I?m new to the R-devel community and still figuring out what is where. If people want to skip my writeup and just look at the code, I?ve made a repository for it here: https://github.com/ahl27/new_dendrapply/tree/master. I?m not quite sure how to integrate it into a fork of R-devel; the package structure is different from what I?m used to. I had written a slightly improved version of dendrapply for one of my research projects, and my advisor encouraged me to submit it to the R project....

...imation. While there will obviously be errors using any approximation, it is possible to use an Edgeworth Expansion correction to uniformly decreases the error in p-value approximation without substantially rewriting the internals. An example patch and benchmarks are available at https://github.com/ahl27/R_Patches/tree/94e8e0bcf5076841637f1031ea9cf456ad18d7ef/EdgeworthExpansion.

The built-in Hodges-Lehmann estimator has some edge cases that...

Dear List, I'm writing to gauge interest in new syntax for positional-only function parameters to be added to R. The pattern of functions accepting other functions as inputs and passing additional ... arguments to them is prevalent throughout the R ecosystem. Currently, however, all such functions must one way or another tackle the problem of inadvertently passing arguments meant to go to

I am a newbie to C (although I did some programming in Perl and Pascal) so forgive me for the language that follows. I am writing because I have a question concerning the *implementation of *(the internal function)* cwilcox* in https://svn.r-project.org/R/!svn/bc/81274/branches/R-DL/src/nmath/wilcox.c. This function is used to determine the test statistics of the Wilcoxon-Mann-Whitney U-test.
