similar to: possible agrep bug; R 2.9.1, Mac OS X 10.5 (PR#13789)

The documentation for agrep says it uses the Levenshtein edit distance, but it seems to get this wrong in certain cases when there is a combination of deletions and substitutions. For example: > agrep("abcd", "abcxyz", max.distance=1) [1] 1 That should've been a no-match. The edit distance between those strings is 3 (1 substitution, 2 deletions), but agrep matches

Happy new year everybody, I'm getting the following while trying to use the agrep() function: > pattern <- "XXX" > subject <- c("oooooo", "oooXooo", "oooXXooo", "oooXXXooo") > max <- list(ins=0, del=0, sub=0) # I want exact matches only > agrep(pattern, subject, max=max) [1] 4 OK > max$sub <- 1 # One allowed

Hi all. This is my first message at R-help...so I'm hoping I have some beginner's luck and get some good help for my problem! FYI I have just started using R recently so my knowledge of R is pretty preliminary. Okay here is what I need help with - I need to know how to use agrep in a for loop. I need to compare elements of a vector of names with other elements of the same vector.

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"

Estimados R-users: Estoy intentando usar la función 'agrep' para hacer búsquedas en cadenas de texto. El parámetro max.distance permite controlar la medida de aproximación de búsqueda de la función de Levenshtein. No obstante, cuando hago búsquedas específicas no obtengo siempre el resultado deseado y no se si es un bug o que no entiendo bien el algoritmo de búsqueda. Por

Hi all, I have two questions 1 - I have the version 1.4.1 of R, and it doesn't have the 'agrep' function in the base library. Is there a way to make this funcion avaliable in R 1.4.1? I mean, how to 'copy' it from R 1.8.1 and 'paste' it in R 1.4.1? 2 - The AGREP function doesn't give me the Levenshtein distance (edit distance). Is there a function in R that does

Hi, I'm trying to use the solve() function in R to invert a matrix. I get the following error, "Lapack routine dgesv: system is exactly singular" However, My matrix doesn't appear to be singular.

What do I need to do to get "install.packages" to work properly for me in R 2.9.1 under Vista? Currently, install.packages in Rgui 2.9.1 by default goes to "C:\\Users\\sgraves\\Documents/R/win-library/2.9". This is a problem for me, because R running under Emacs does not currently look there. I made the mistake last night of first installing R 2.9.1 in the

Should one expect minor numerical differences between 64bit and 32bit R on Windows? Hunting around the lists I've not been able to find a definitive answer yet. Seems plausible using different precision arithmetic, but waned to confirm from those who might know for sure.

Hi, (I am not longer on R-devel - please CC:) Just when Fedora 11 is shipping a gcc 4.4 based cross-compiler - the last major distro to ship a cross-compiler, but the first to ship a gcc 4.4- one.(both Suse & Debian has been so so for a while, and I expect Ubuntu as well), and the mingw people has finally released gcc 4.4 mingw builds, I am a little disappointed to find that cross-compling

Hi, I have just updated R from version 2.8.1 to version 2.9.1. I am running Windows XP Professional, Service Pack 3. With the update, I decided to update a set of packages that I maintain by compiling them for the new version. Everything worked fine except for one package. This package is unique (among the six I was working on) in that is stored on a UNIX-based file server that is

I am still running 2.9.0 and came across a package that was built with 2.9.1. I got a warning upon loading the package. I tried to launch a function from such a package. It seems to hang up. I can't believe it takes forever. I am resolved to upgrade my R version to the newest one. But on a Windows box I do not know how to unistall the current version in advance of installing the new one.
