Strings are not glamorous, high-profile components of R, but they do play a big role in many data cleaning and preparations tasks. R provides a solid set of string operations, but because they have grown organically over time, they can be inconsistent and a little hard to learn.

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.

Last line in the following (updated) code produces the error require(raster) require(rts) require(stringr) r <- raster(ncol=100, nrow=100) values(r) <- runif(ncell(r)) stack(r)->s r->rs for(i in 1:23){ rs[]<-r[]*i addLayer(s,rs)->s print(nlayers(s)) } dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12)))

I am trying to count the number of times a word occurs in a string. and using str_count function from the package stringr. This function counts the substrings as well. Is there a way in which I can exclude the substring count and just take the exact match. Thanks in advance. -- Thanks and Regards Agrima Srivastava -------------------------------------------------------------------------------

Which function was being evaluated to produce the error? I don't see

I can't test that at the moment as I don't have the libraries. Perhaps later.

Dear Raju I agree to Dirk 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

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 when trying to run the unit tests %
