## Default S3 method:
filterID(text, id, ...)

## S3 method for class 'textmeta'
filterID(object, id, filtermeta = TRUE, ...)

Arguments

...	Not used.
text	Not necassary if object is specified, else should be object$text: list of article texts
id	Character: IDs the corpus should be filtered to.
object	A textmeta object

Teach a Man To Fish, and You Feed Him for a Lifetime",
B="So Long, and Thanks for All the Fish",
C="A very able manipulative mathematician, Fisher enjoys a real mastery
in evaluating complicated multiple integrals.")

meta <- data.frame(id = c("C", "B"), date = NA, title = c("Fisher", "Fish"),
stringsAsFactors = FALSE)
tm <- textmeta(text = texts, meta = meta)

filterID(texts, c("A", "B"))
filterID(texts, "C")
filterID(tm, "C")
filterID(tm, "B")
filterID(tm, c("B", "A"), FALSE)
