Dear R-experts, I just tracked down a nasty bug in a dynamically parametrized function to wrong argument matching. As we get more and more complex applications build on top of R (like bioconductor) partial matching gets more and more dangerous. I would like to deactivate partial matching in R (partial argument matching as well as partial matching of list elements), e.g. using an environment

Hi, I'm very new to R, and am not at all a software programmer of any sort. I appreciate any help you may have. I have figured out how to get my data into a dataframe and order it alphabetically according to a particular column. Now, I would like to seperate out certain rows based on partial character matches. Here is an (extremely) abreviated example of my data set Probe Ch1

Hi All, I am trying to match two character arrays (email lists) using either pmatch(), match() or charmatch() functions. However the function is "missing" some matches due to differences in the cases of some letters between the two arrays. Is there any way to disable case sensitivity or is there an entirely better way to match two character arrays that have identical entries but written

Sorry about the odd terminology, but I suspect that my intent might be completely missed had I used "aggregate" or "classify" (each of which appears to have some rather special meanings in statistical analysis and modeling). I have some data about software builds; one of the characteristics of each is the name of the branch. A colleague has generated some fairly interesting

Hello, It's just a strange coincidence that someone posted just very recently a question about matching. I know there are several match function in the base package (such as match, pmatch, charmatch, and the gsub etc) but I can't seem to use them wisely to be able to get what I need. suppose I have the following strings: "tets" "estt" "rtes7"

In a number of places internal to R, we need to know which files have changed (e.g. after building a vignette). I've just written a general purpose function "changedFiles" that I'll probably commit to R-devel. Comments on the design (or bug reports) would be appreciated. The source for the function and the Rd page for it are inline below. ----- changedFiles.R: changedFiles

Hi, I am trying to install Xen 3.1.3 from the source code. The machine on which I would like to install it doesn''t have access to the Internet. So I did a "make world" on a different machine, copied the files to where I actually wanted to install Xen and then re-built and installed it. However, when I boot into the new kernel and try to execute "xm" or

Dear Ivan, thanks a lot, that is helpful. Still, I feel that default partial matching cripples the functionality of data.frame for larger tables.

Changing the default now would require a long deprecation cycle to give everyone who uses `[.data.frame` and relies on partial matching (whether they know it or not) enough time to

Hi Hilmar and Ivan, I have used your code examples to write a blog post about this topic, which has figures that show the asymptotic time complexity of the various approaches, https://tdhock.github.io/blog/2023/df-partial-match/ The asymptotic complexity of partial matching appears to be quadratic O(N^2) whereas the other approaches are asymptotically faster: linear O(N) or log-linear O(N log N).

Hello, I''m trying to compile Xen unstable on NetBSD, I''ve aplied the patches from http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/xentools41/patches/?only_with_tag=MAIN and copied the blk files from http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/xentools41/files/?only_with_tag=MAIN (I don''t know which of these patches have been applied to xen unstable, so

I am using R0.64.1 under Windows 95. The help for `pmatch' states that: If `duplicates.ok' is false multiple matches will result in the value of `nomatch' being returned, and if it is true, the index of the first matching value will be returned. The help for pmatch gives the following examples: pmatch("m", c("mean",

I really think this is a Windows problem, but since my very good friend Bill refuses to return my calls ...

The client will happily JOIN the domain, but my

Hi all, This occurred in R-2.11.0 (WinXP). The R-help page of .[ says that: "Character indices can in some circumstances be partially matched (see pmatch) to the names or dimnames of the object being subsetted (but never for subassignment). Unlike S (Becker et al p. 358)), R has never used partial matching when extracting by [, and as from R 2.7.0 partial matching is not by default used by

Hi, I'm using the "ncdf" library for creating ncdf files. But I need to create about 100 variables per file (e.g. single rivers), So I do not like to create each variable separately. Unfortunately I found no way to make this work, as I'm unable to create a correct list of class "var.ncdf". ###code piece river=list(mode='var.ncdf', length=nriv)
