readability.num: Calculate readability

Description

This function is a stripped down version of readability. It does not analyze text, but directly takes the values used by the formulae to calculate the readability measures.

Usage

readability.num( txt.features=list( sentences=NULL,
    words=NULL, letters=c(all=0, l5=0, l6=0),
    syllables=c(all=0, s1=0, s2=0), punct=NULL,
    all.chars=NULL, prepositions=NULL, conjunctions=NULL,
    pronouns=NULL, foreign=NULL, TTR=NULL,
    FOG.hard.words=NULL, Bormuth.NOL=NULL,
    Dale.Chall.NOL=NULL, Harris.Jacobson.NOL=NULL,
    Spache.NOL=NULL), index=c("ARI", "Bormuth", "Coleman",
    "Coleman.Liau", "Dale.Chall", "Danielson.Bryan",
    "Dickes.Steiwer","DRP", "ELF", "Farr.Jenkins.Paterson",
    "Flesch", "Flesch.Kincaid", "FOG", "FORCAST", "Fucks",
    "Harris.Jacobson", "Linsear.Write", "LIX", "nWS",
    "RIX", "SMOG", "Spache", "Strain", "Traenkle.Bailer",
    "TRI", "Wheeler.Smith"), parameters=list(), ...)

Arguments

txt.features

A named list with statistical information on the text, or an object of class kRp.readability (only its desc slot will then be used). Valid values are: [object Object],[object Object],[object Object],[object Object],[object

index

A character vector, indicating which indices should actually be computed.

parameters

A named list with magic numbers, defining the relevant parameters for each index. If none are given, the default values are used.

...

Additional options, see readability.

Examples

test.features <- list(
 sentences=18,
 words=556,
 letters=c(all=2918, l1=19, l2=92, l3=74, l4=80, l5=51, l6=49),
 syll=c(all=974, s1=316, s2=116),
 punct=78,
 all.chars=3553,
 prepositions=74,
 conjunctions=18,
 pronouns=9,
 foreign=0,
 TTR=0.5269784,
 Bormuth=192,
 Dale.Chall=192,
 Harris.Jacobson=240,
 Spache=240)

# should not calculate FOG, because FOG.hard.words is missing:
readability.num(test.features, index="all")
