findlines: Find lines in a bunch of files

In sachserf/sf: Collection of miscellanous functions

Find lines in a bunch of files

Description

Works like grep or which for a bunch of files (line by line). Useful example: 1. Always use the same predefined word(s) to mark positions in scripts where you should review something at some time (e.g. 'TODO'). 2. Search for those words within a bunch of files to get an overview.

Usage

findlines(
  expression = "# magic word",
  exclusive = FALSE,
  path = ".",
  filepattern = "\\.R$|\\.Rmd$",
  recursive = TRUE
)

Arguments

expression	Character. Specify expression to match the line.
exclusive	Logical. If TRUE use which, else grep.
path	Character. Specify path to the directory including the files.
filepattern	Character. Specify file pattern.
recursive	Logical.

Note

If exclusive == FALSE you can use regular expressions (and therefore multiple expressions at a time).
