I am trying to learn how to run the unit tests in the stringr package and have the following questions. 1) The r-cran-stringr package does not suggest/depend on the r-cran-testthat package . Would it make sense to add such a thing since after all the tests in /usr/lib/R/site-library/stringr/tests rely on testthat package? 2) I am getting the following error...

Hi Group, I have a question on Stringr package I have a table like this X Y ab su - di ac pi - tu ad tu - tu I want output like this X Y ab su ab di ac pi ac tu ad tu ad tu I am wondering if this operation can be done using stringr package (only) ? [[alter...

...irk that this is not really the best place for these matters, but as I got curious, I checked and found you should use test_package() and not test_dir(), as the latter does not load unexported functions of the package (such as check_string()) that may occur in the tests. For packaging of r-cran-stringr, it is probably most efficient to file a bug report there because of the missing Suggests for r-cran-testthat. Kind regards, Johannes Am Sonntag, 19.

...ions, but because they have grown organically over time, they can be inconsistent and a little hard to learn. Additionally, they lag behind the string operations in other programming languages, so that some things that are easy to do in languages like Ruby or Python are rather hard to do in R. The `stringr` package aims to remedy these problems by providing a clean, modern interface to common string operations.

Estoy intentándolo con stringr y usando expresiones regulares, pero no doy con la tecla. Seguro que es fácil He probado algo como require(stringr) str_extract(datos$tipo,"[p][A-Za-z]+") Pero me devuelve todo NA.. ¿Alguna idea o sitio dónde pueda aprender algo sobre expresiones regulares? Saludos

I figured it out, at least enough to get rgeos's gSimplify function to work, which was my original goal; the stringr problem was with 0.2, however I got stringr 0.5 to install by changing the minimum version in DESCRIPTION from R2.11 to R 2.10. ...

...should carefully read the docs, see ?regexp. You really do not want to pass a multi-element vector as 'keywords' in this case, but instead: stri_count_regex(text3, "[0-9]+\\) ") or: stri_count_regex(text3, "[[:digit:]]+\\) ") BTW, I do not understand why to use the stringr package if it is just a wrapper around the stringi package.

Hi all, I have a large number of text strings to search for enumerated items. However, I am receiving this error message even though I thought that I properly escaped the special character closed parenthesis: > Count<-str_count(text3,keywords) Error in stri_count_regex(string, pattern, opts_regex = opts(pattern)) : Syntax error in regexp pattern.

...for the instance names (e.g. competition01, competition13, small_1, big_20, med_9). What I want to be able to sort them first in category order so: competition < small < med < big, and then perform the secondary ordering by the final one or two digits. I've used Hadley Wickham's StringR package to split the names into the string and numeric sections so I could get those ordered easily enough. What I'm struggling with is how to sort the categories (because I don't want them in a straight alphabetic order). library(stringr) d <- data.frame(instance = c("competition1...
