Parse parts of path for text analysis — parse

parse_path() parses parts of a path, i.e., anything separated by "/", "-", "_" or ".", and adds them as a new variable. Parts that do not consist of letters only, or of a real word, can be filtered via the argument keep.

Usage

parse_path(wt, varname = "url", keep = "letters_only", decode = TRUE)

Arguments

wt: webtrack data object
varname: character. name of the column from which to extract the host. Defaults to "url".
keep: character. Defines which types of path components to keep. If set to "all", anything is kept. If "letters_only", only parts containing letters are kept. If "words_only", only parts constituting English words (as defined by the Word Game Dictionary, cf. https://cran.r-project.org/web/packages/words/index.html) are kept. Support for more languages will be added in future.
decode: logical. Whether to decode the path (see utils::URLdecode()), default to TRUE

Value

webtrack data.frame with the same columns as wt and a new column called 'path_split' (or, if varname not equal to 'url', '<varname>_path_split') containing parts as a comma-separated string.

Examples

if (FALSE) { # \dontrun{
data("testdt_tracking")
wt <- as.wt_dt(testdt_tracking)
wt <- parse_path(wt)
} # }
