R: Search the quote database for a string or regex pattern

search_quotes {statquotes}

R Documentation

Search the quote database for a string or regex pattern

Description

This function takes a search pattern (or regular expression) and returns all quotes that match the pattern.

A convenient wrapper for search quotes that by default returns all quotes

Usage

search_quotes(
  search,
  ignore_case = TRUE,
  fuzzy = FALSE,
  fields = c("text", "source", "tags", "cite"),
  ...
)

search_text(search, fuzzy = FALSE, ...)

get_quotes(search = ".*", ...)

Arguments

`search`	A character string or regex pattern to search the database.
`ignore_case`	If `TRUE`, matching is done without regard to case.
`fuzzy`	If `TRUE`, use `agrep` to allow approximate matches to the search string.
`fields`	A character vector of the particular fields to search. The default is `c("text","source","tags")`. You can use the shortcut `fields="all"` to search all fields (including citation, url).
`...`	additional arguments passed to `agrep` to fine-tune fuzzy search parameters.

Value

A data frame (also with class 'statquote') object containing all quotes that match the search parameters.

A data frame (also with class 'statquote') object containing all quotes.

Examples

search_quotes("^D") # regex to find all quotes that start with "D"
search_quotes("Tukey") # all quotes with "Tukey"
search_quotes("Turkey", fuzzy = TRUE) # fuzzy match

# to a data.frame
out <- search_quotes("bad data", fuzzy = TRUE)
as.data.frame(out)

search_text("omnibus")
qdb <- get_quotes()
nrow(qdb)
names(qdb)
