...ing against long strings. - Substitutions can be functions as well as strings. - Matches can be efficiently obtained over only part of the strings. - Fewer core functions, with more consistent names. The package is developed using GitHub, and more information can be found at <https://github.com/jonclayden/ore>. It is also available on CRAN. In addition, I've developed a regular expression benchmark, which pits "ore", "base" and the "stringi" package against the full text of The Adventures of Sherlock Holmes. It can be obtained and run via <https://github.com/...

It will be updated after each release of R. The code used to generate these versions is freely available at <https://github.com/jonclayden/r-manuals>. I hope some people find this useful. Comments are welcome. All the best, Jon

...oes not seek to the requested location. It doesn't seem to occur all the time - I tried to create a small example file to illustrate it, but the problem didn't occur.

...mmand, but I'm not sure how portable that will itself be. Could anyone advise on the best way to make this work portably, please? For this application I'm not concerned about Windows compatibility - portability across Unix-alikes is sufficient. The source code is at < https://github.com/jonclayden/tractor/blob/master/src/tractor.c>, if that is useful. All the best, Jon [[alternative HTML version deleted]]

Hi, when running a R-script like this: enable_magic() compute_stuff() disable_magic() the whole script is parsed into a single expression and then evaluated, whereas when using the interactive shell after each line entered, a REPL loop happens. Is there a way to make a script evaluation behave like this, because I need a single REPL iteration for every expression in the script. It doesn't
