FindReplace: Find/Replace text in a file

Description

Usage

FindReplace(file, find, replace)
Rnw2Rmd(file)
UseTemplate(file, find=NULL, replace=NULL)
UseTemplateList(newfile, fileList, find=NULL, replace=NULL)

Value

FindReplace will replace the existing file with the updated version while UseTemplate will return a character string which will usually be pushed out to an R script or R markdown file.

The external (text) file, template, or list of templates to be updated.

newfile

the file to write output to

find

The text to remove.

replace

Details

The FindReplace function is purely intended for use on an external file whereas UseTemplate is intended to take a template file from within the BrailleR package and return the updated text to the calling environment.

Rnw2Rmd tries to replace Standard LaTeX commands and Sweave chunk headers with R markdown ones. It is NOT comprehensive, but it does get a long way towards a useful markdown file.

Obviously the specified file must exist for these functions to work.

Examples

UseTemplate("DTGroupSummary.R")
UseTemplate("DTGroupSummary.R", "DataName", "MyData")
