Get dictionary information

Source: R/RcppExports.R
dictionary_info.Rd

Returns all dictionary information under the current configuration.

Arguments

sys_dic

Character scalar; path to the system dictionary for 'MeCab'.

user_dic

Character scalar; path to the user dictionary for 'MeCab'.

Value

A data.frame (an empty data.frame if there is no dictionary configured at all).

Details

To use the tokenize() function, there should be a system dictionary for 'MeCab' specified in some 'mecabrc' configuration files with a line dicdir=<path/to/dir/dictionary/included>. This function can be used to check if such a configuration file exists.

Currently, this package detects 'mecabrc' configuration files that are stored in the user's home directory or the file specified by the MECABRC environment variable.

If there are no such configuration files, the package tries to fall back to the 'mecabrc' file that is included with default installations of 'MeCab', but this fallback is not guaranteed to work in all cases.

In case there are no 'mecabrc' files available at all, this function will return an empty data.frame.

Note that in this case, the tokenize() function will not work even if a system dictionary is manually specified via the sys_dic argument. In such a case, you should mock up a 'mecabrc' file to temporarily use the dictionary. See examples for build_sys_dic() and build_user_dic() for details.

Examples

if (FALSE) { # \dontrun{
dictionary_info()
} # }
