...ow. i need to distribute the DESCRIPTION.in file, as ./configure will need it. but, "R CMD check" wants to look at DESCRIPTION, so i've let that also come into the package tarball. however, when i run "R CMD check" with DESCRIPTION.in in the tree, it fails: ---- bash greg-minshalls-mbp: {3359} R CMD check image2k_0.1.tar.gz * using log directory ?/Users/minshall/src/mine/image2k/buildit/image2k.Rcheck? * using R version 3.0.3 (2014-03-06) * using platform: x86_64-apple-darwin13.1.0 (64-bit) * using session charset: UTF-8 Error in if (desc["Priority"] == "base...

hi. i'd like to instantiate sed(1), send it some input, and retrieve its output, all via pipes (rather than an intermediate file). my sense from pipe and looking at the sources (sys-unix.c) is that is not possible. is that true? are there any thoughts of providing such a facility? cheers, Greg

Chuck and Greg, Thanks a lot for your help! I have a much better understanding now of what is happening ?under the hood?.

..."groups" don't work as required. Unfortunately being at a University I don't get to control the environment tightly, unless someone knows of a way of banning OS X 10.5 clients server side. The issue is that MacOS X 10.6 won't create symlinks. That is 10.4 and 10.5 create the Minshall & French style symlink, but 10.6 just gives an error. The symlinks are used in login hooks to redirect certain folders on network home directories to the local disk. Consequently getting them to work is important. We tried a perl script that created correctly formatted Minshall & French 10...

...k). i'm curious how people move from their personal development tree to a tree from which the package can be passed to "R CMD *". do "you" have a makefile in their tree that creates this? during development, is this the path you use for building and testing? cheers, Greg Minshall

hi. i'm working on a package which only works if one (or both) of two libraries (Imlib2 and MagickWand) exist on the machine on which the package is compiled and executed. as currently written, the program purposely generates an error at *compile* time if neither library is available (thinking the earlier the user is notified, the less frustrating). is there a way of specifying this

I'm using samba because it should also work with OSX. Well there's a workaround called "Minshall/French" symlink format: https://lists.samba.org/archive/samba-technical/2014-September/102476.html that hides the symlink target inside a 'special' file. That should still work over SMB2, but it's tunnelling stuff inside the protocol, not really protocol support. It's what t...

...allow that kind of thing, but again R (and everyone else, I think?) doesn't do so for regular doubles. Also, I would expect the year 1e50 and the "year" Inf to be functionally equivalent in meaning (and largely meaningless) in context.

Gabor, thanks. yes, managing the two-way communication is always a bit error-prone, as it depends on the input/output characteristics of the two ends -- they either match, or deadlock. it's too bad if polling is always *required* -- i'd think sometimes a programmer would be happy blocking, though other times one wants better control over when to block. cheers, Greg

Hello all, I am trying to get a better understanding of the underlying code for the stats::dpois function in R and, specifically, what happens under the hood when it is called. I finally managed to track down the C course at: https://github.com/wch/r-source/blob/trunk/src/nmath/dpois.c. It would seem that the dpois C function is taking a double for each of the x and lambda arguments so I am a bit

...ms like a good candidate. but, i run nmh, not dovecot. as i started install it (on arch linux), i started to worry that it may be foolish of me to try to run it outside of a dovecot system. any wisdom about that would be gratefully received. thanks in advance, and thanks for the software.

hi. i've looked for (and not found) an assert() function. needing one, i created the following (from stop()). i'm posting it in case 1) someone sees a problem with this; and 2) someone else has a need. cheers, Greg ---- ## an assert mechanism... assert <- function (shouldbe, ...) { if (!shouldbe) { .Internal(stop(as.logical(TRUE),

...this would probably involve changes to socketConnection as well as maybe the internet module, so is probably longer term. i think, though, that doing this would benefit people who now are confused when they can't start up two clusters on the same (currently, master) machine, etc. cheers, Greg Minshall
