synonym.frame

A dataframe or environment containing a dataframe of positive/negative words and weights.

synonym.list

A named list of lists (or vectors) of synonyms.

envir

logical. If TRUE a lookup table (a dataframe within an environment) is produced rather than a data.frame.

Examples

synonyms(c("the", "cat", "job", "environment", "read", "teach"))
head(syn(c("the", "cat", "job", "environment", "read", "teach"),
    return.list = FALSE), 30)
syn(c("the", "cat", "job", "environment", "read", "teach"), multiwords = FALSE)

## User defined synonym lookup
syn_dat <- list(
    like = list(c("want", "desire"), c("love", "care")),
    show = list(c("reveal"), c("movie", "opera")),
    R = c("old friend", "statistics language")
)

synonyms_frame(syn_dat)
synonyms_frame(syn_dat, envir=FALSE)
syn(c("R", "show"), synonym.frame = syn_frame(syn_dat))

syns.hash <- syn_frame(syn_dat, prior.frame = SYNONYM)
syn(c("R", "show", "like", "robot"), synonym.frame = syns.hash)
