Re: [Rd] Feature request: non-dropping regmatches/strextract
After some discussion within R core, we decided that a "nomatch" argument on regmatches() may be a good initial step. We might add a new function later that combines the regexpr() and regmatches() steps. The gregexpr() and regexec() inputs are both lists so it's not clear whether a "nomatch" value would be relevant (the elements are empty) in those cases.

I think that's a good reason for not including this in regmatches; you're right, its name is somewhat suggestive of yielding matches. Also, that sounds like a great design for strcapture with an atomic prototype. Best, CG __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Yes, but output depends on evaluation as well as precedence. Seeing different things wasn't an immediate surprise. Your own parse() examples are much clearer; thanks for that.

[Bioc-devel] Build error due to TensorFlow installation
Dear all, since I replaced some old C++ code with TensorFlow I am getting some build errors on merida1 and tokay1 regarding installation (even though I install TF and TF Probability during /.onLoad/) http://bioconductor.org/checkResults/devel/bioc-LATEST/netReg/merida1-buildsrc.html Does anyone know how I can fix this or did anyone use TF with Bioconductor so far? Many thanks in advance. Best, Simon [[alternative HTML version deleted]] ___ Bioc-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/bioc-devel
[Rd] rbind returns a zero row data frame when binding zero column data frames
Dear all, `rbind()` returns a zero row data frame when binding zero column data frames, see example below: ``` r # a data frame with 1 row and 0 column x <- data.frame(row.names=1) x #> data frame with 0 columns and 1 row rbind(x,x) #> data frame with 0 columns and 0 rows ``` I would have expected in that case `data frame with 0 columns and 2 rows`. `cbind()` on the other hand acts as I would expect, returning a 2 column data frame from 2 one column data frames even if they have no row. ``` r # a data frame with 0 row and 1 column y <- data.frame(A = numeric(0)) y #> [1] A #> <0 rows> (or 0-length row.names) cbind(y,y) #> [1] A A #> <0 rows> (or 0-length row.names) ``` [[alternative HTML version deleted]] __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
Re: [R-pkg-devel] URL of a frame (or a vignette)?
I personally would not link to rdocumentation. They update packages rather erratically and the information can be months or even years old, without any indication. The drop down list "Other versions" at the top of the package page is a misnomer, it should be "Older versions". My main objection though is that, in my opinion, they blatantly disrespect the GPL license. Their pages are like a trap, with all their links pointing back to their site. They do not put even a link to CRAN, the place where they take the files from. Even the authors' names are linked them! The only way to ensure a prominent link to CRAN is to have a badge or link at the top of the README file, which they show. This is one of the reasons a put a CRAN badge at the top of my README file, even though it looks strange on CRAN. I alerted them about this a couple of years ago in their 'Comments' area but they did not respond.

Re: [Rd] New lazyload rdx key type: list(eagerKey=, lazyKeys=)

All the ones I've seen involve the environment in srcref attributes and most packages do not keep that. Will these be used for more sorts of environments in the future? The new mechanism allows to load lazily selected bindings from an environment - previously only the bindings from the package/namespace environment were loaded lazily. The mechanism is currently used only for "lines" and "parseData" bindings of "srcfile" environments. Packages that include parse data will benefit from the latter and all packages that include source references will benefit from both. This change made it feasible to run package checks with source references enabled, so now one can get more useful error traces with execution time overhead reasonable for check runs. The format of the lazy loading database is specific to R release, it can change at any time. Specifically this mechanism could be used for more environments, but I am not aware of any that would benefit at the moment. What is the meaning of the lazyKeys? Are these stored as promises until needed or is there some special option to never or always load them? Bindings listed in lazyKeys are treated the same way as bindings in the package/namespace environment, so they become promises after loading the environment. Those promises load the individual objects for the bindings when forced (details in makeLazyLoad.R and lazyLoad.R and now also explicitly in R-ints).
