rename_r_to_R: Rename files' extensions in a folder from .r to .R

Description

Rename files' extensions in a folder from .r to .R.

Usage

rename_r_to_R(subdir = ".", recursive = FALSE, message = TRUE,
  text_to_find = "\\.r$", new_extension = ".R", ...)

Arguments

subdir

(character) sub folder from the current working directoryl in which the files should be changed. Default is "".

recursive

(logical) FALSE. Should the function keep going into folders and check them as well?

message

(logical) should we output how many files were changed. (default is FALSE)

text_to_find

old file extension (should have $ at the end!)

new_extension

new file extension...

...

not used.

Value

(integer) the number of files changed

Details

This came after a discussion with Hadley, JJ, and Martin leading to the realization that since we are using the R language (and not the r language), the standard is to use .R files instead of .r

Be careful when using the recursive argument. And remember that source("miao.r") and source("miao.R") Are NOT the same...

Examples

# NOT RUN {
rename_r_to_R() # changes only .r in the current wd
rename_r_to_R("R") # fixing the file ending inside a package directory
rename_r_to_R(recursive = TRUE) # Changes 
rename_r_to_R(recursive = TRUE, message = FALSE) # Changes 
# ALL of the .r files underneath the current 
# working directory

# First run the following in git bash:
# git config core.ignorecase false
rename_r_to_R(recursive = TRUE, text_to_find="\\.R$", new_extension = ".b")

# mmm, since it does not work nicely, you'd need to run the following:
# and commit between the two.
rename_r_to_R(recursive = TRUE, text_to_find="\\.r$", new_extension = ".b")
# commit!
rename_r_to_R(recursive = TRUE, text_to_find="\\.b$", new_extension = ".R")

# }
