recode_delete: Remove one or more codes

Description

These functions remove one or more codes from a source, and make it easy to justify that decision.

Usage

recode_delete(
  input,
  codes,
  filter = TRUE,
  output = NULL,
  filenameRegex = ".*",
  outputPrefix = "",
  outputSuffix = "_rcDeleted",
  childrenReplaceParents = TRUE,
  recursiveDeletion = FALSE,
  decisionLabel = NULL,
  justification = NULL,
  justificationFile = NULL,
  preventOverwriting = rock::opts$get("preventOverwriting"),
  encoding = rock::opts$get("encoding"),
  silent = rock::opts$get("silent")
)

Arguments

input

One of 1) a character string specifying the path to a file with a source; 2) an object with a loaded source as produced by a call to load_source(); 3) a character string specifying the path to a directory containing one or more sources; 4) or an object with a list of loaded sources as produced by a call to load_sources().

codes

A character vector with codes to remove.

filter

Optionally, a filter to apply to specify a subset of the source(s) to process (see get_source_filter()).

output

If specified, the recoded source(s) will be written here.

filenameRegex

Only process files matching this regular expression.

outputPrefix

The prefix and suffix to add to the filenames when writing the processed files to disk, in case multiple sources are passed as input.

outputSuffix

The prefix and suffix to add to the filenames when writing the processed files to disk, in case multiple sources are passed as input.

childrenReplaceParents

Whether children should be deleted (FALSE) or take their parent code's place (TRUE). This is ignored if recursiveDeletion=TRUE, in which case children are always deleted.

recursiveDeletion

Whether to also delete a code's parents (TRUE), if they have no other children, and keep doing this until the root is reached, or whether to leave parent codes alone (FALSE). This takes precedence over childrenReplaceParents.

decisionLabel

A description of the (recoding) decision that was taken.

justification

The justification for this action.

justificationFile

If specified, the justification is appended to this file. If not, it is saved to the justifier::workspace(). This can then be saved or displayed at the end of the R Markdown file or R script using justifier::save_workspace().

preventOverwriting

Whether to prevent overwriting existing files when writing the files to output.

encoding

The encoding to use.

silent

Whether to be chatty or quiet.

Value

Invisibly, the recoded source(s) or source(s) object.

Examples

# NOT RUN {
### Get path to example source
examplePath <-
  system.file("extdata", package="rock");

### Get a path to one example file
exampleFile <-
  file.path(examplePath, "example-1.rock");

### Load example source
loadedExample <- rock::load_source(exampleFile);

### Delete two codes, moving children to the codes' parents
recoded_source <-
  rock::recode_delete(
    loadedExample,
    codes=c("childCode2", "childCode1"),
    silent=FALSE
  );

### Process an entire directory
list_of_recoded_sources <-
  rock::recode_delete(
    examplePath,
    codes=c("childCode2", "childCode1"),
    silent=FALSE
  );
