Dear R-Users,
Does anyone know any package or library that implements functions for word wrapping? I did implement a very rudimentary one (Github link below), but would like to avoid to reinvent the wheel. Considering that word-wrapping is a very common task, it should be available even in base R (e.g. in a "format" module/package). Sincerely, Leonard ======= The latest versions of the functions are on Github: https://github.com/discoleo/R/blob/master/Stat/Tools.CRAN.R # Note: # - the function implementing word wrapping: split.N.line(...); # - for the example below: the functions defined in Tools.CRAN.R are required; Examples: ### Search CRAN library(pkgsearch) searchCran = function(s, from=1, len=60, len.print=20, extend="*", sep=" ", sep.h="-") { if( ! is.null(extend)) s = paste0(s, extend); x = advanced_search(s, size=len, from=from); if(length(x$package_data) == 0) { cat("No packages found!", sep="\n"); } else { scroll.pkg(x, len=len.print, sep=sep, sep.h=sep.h); } invisible(x) } # with nice formatting & printing: x = searchCran("text", from=60, sep.h="-") scroll.pkg(x, start=20, len=21, sep.h = "-*") # test of sep.h=NULL vs ... Notes: 1.) split.N.line: - was implemented to output a pre-specified number of lines (kind of "maxLines"), but this is not required from an actual word-wrapper; - it was an initial design decision when implementing the format.lines() function; but I plan to implement a 1-pass exact algorithm during the next few days anyway; 2.) Refactoring - I will also move the formatting code to a new file: probably Tools.Formatting.R; - the same applies for the formatting code for ftable (currently in file Tools.Data.R); 3.) Package gridtext - seems to have some word-wrapping functionality, but does not seem to expose it; - I am also currently focused on character-based word wrapping (e.g. for RConsole); [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
