similar to: Muliple partial matches with pmatch

The pmatch help (see also section 4.3.2 in the R Language Definition) claims that pmatch with duplicates.ok=FALSE provides the same functionality as R's argument matching algorithm, modulo how empty strings are matched. Here's an undocumented inconsistency between pmatch and R's argument matching algorithm: > sessionInfo() R version 3.0.1 (2013-05-16) Platform:

I have two supposedly identical installations, one under Windows 95, and the other (at home) under Windows 98. The puzzle is that under my Windows 98 installation, symbols plotted by default or with pch come out huge, at about 2.2 times the height of the axis labels. Setting cex=0.5 seems about what is needed to fix the heights. On the Windows 95 installation, the symbols come out just a little

Hello R Helpers, Business - 64 bit windows 7, R 2.11.1 I am trying to match the character contents of one list, called 'exclude', to those of a second list, called 'dataset' dataset is a list of file names with folder locations, and looks like this when called: > dataset [1] "A/10-10-29a-13.cdf" "A/10-10-29a-14.cdf" "A/10-10-29a-15.cdf"

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, I wonder if there's a good intro to the pattern matching using R? I'm a perl programer and find it too confusing and complex to use regular expressions under R. For instance, why does pmatch("d","ad") returns NULL? How would I call the functions in order to match any portion of the string? Under what circumstances shall backslush be used? I try to extract all

Depending on the setting of par()$usr, the 'at' setting in mtext(.., adj=0, outer=T) may cause the text to appear in an anomalous position (e. g. in the first instance below, at the left of the plot region rather than at 'at=0' in the figure region), or the text may not appear at all. If one does not set the 'at' parameter the text appears (with 'adj=0') on the

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).

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

Is there an equivalent to the S-PLUS par()$cxy in R? Also, is it possible to get notice taken of some equivalent of \n in R when using text()? For what it is worth I am using RW-0.64.1.

Incidentally I noted Brian's comment that R had misread his character dimension information wrongly.

Hi, Somebody asked me to make sure that all the machines running the in our lab (XP and Linux, both running 2.0) have R installed and that A) All the packages are installed and B) kept up-to-date.

Following p.206 of "Statistical Models in S", I wish to change the code for summary.glm() so that it estimates the dispersion for binomial & poisson models when the parameter dispersion is set to zero. The following changes [insertion of ||dispersion==0 at one point; and !is.null(dispersion) at another] will do the trick: "summary.glm" <- function(object, dispersion =
