Examples

## Read a thesaurus for taxa:
thesaurusFile <- system.file("extdata", "taxonThesaurus.csv", package="zoolog")
thesaurus <- ReadThesaurus(thesaurusFile)
## The attributes of the thesaurus include the fields 'caseSensitive',
## 'accentSensitive', and 'punctuationSensitive', all FALSE by default.
attributes(thesaurus)

## Any of them can be set by the user if desired:
thesaurus2 <- ReadThesaurus(thesaurusFile, accentSensitive = TRUE)
attributes(thesaurus2)

## Write the thesarus to a file:
fileExample <- file.path(tempdir(), "thesaurusExample.csv")
WriteThesaurus(thesaurus, fileExample)
## Replace tempdir() for your preferred local path if you want to easily
## examine the written file.

## Read a thesaurus set:
thesaurusSetFile <- system.file("extdata", "zoologThesaurusSet.csv", package="zoolog")
thesaurusSet <- ReadThesaurusSet(thesaurusSetFile)
## The attributes of the thesaurus set include information of the constituent
## thesauri: names, source file names, and their mode of application on datasets.
attributes(thesaurusSet)
## The attributes of each thesaurus are also set by 'ReadThesaurusSet'.
attributes(thesaurusSet$measure)

## Write the thesaurus set to a file:
fileSetExample <- file.path(tempdir(), "thesaurusSetExample.csv")
WriteThesaurusSet(thesaurusSet, fileSetExample)
## It writes the thesaurus-set main data frame and each of the included
## thesaurus files.
## Again, replace tempdir() for your preferred local path if you want to
## easily examine the written files.
