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

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. 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.

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

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"

Hi, I have to match names where names can be recorded with errors or additions. Now I am searching for a string search function which returns always the "closest" match. E.g. searching for "Washington" it should return only Washington but not Washington, D.C. But it also could be that the list contains only "Hamburg" but the record I am searching for is

Good Afternoon R Community, I often work with very large data bases and want to search for select cases by a particular word or numeric value. I created the following simple function to do just that. It searchs a particular column for the phrase and returns a data frame with the rows that contain that phrase (for a particular column). Search<-function(term, dataframe, column.name,

The following creates a point process version of a sinewave (maybe there's a better way): p<-amp*cos(2*pi*freq*(1:n)/n ) + 0.5 as.numeric(runif(1:n)<p) I get something like this: 1 o oo oo o o ooooo o 0 ooo o o o o o ooo ooo In case it's not obvious, this is a noisy version of 1 ooooooo ooooooo 0 ooooooo

I've tried it with --with-f2c and with f96 (NAG Fortran compiler) in and out of my $PATH. Can you verify that the configure script works for you without the --with-f2c option?

A big compile time regression. Any ideas? Ciao, Duncan.

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, I've been trying to get a shared library version of the R package(version 2.12.1) installed on a CentOS 5 system. (It installs fine without but other packages demand shared libs - namely Rapache). I've tried this with yum but don't know of any flags to set to tell it to installl with shared libs enabled. I then tried a local R install as non-root with source packages: after
