abdData

Find data in Analysis of Biological Data

Description

A utility function to assist users to locate data sets in Analysis of Biological Data within the abd package.

Usage

abdData(..., chapters = 1:21, types = c("Example", "Problem"),
  numbers = 1:100, pattern = "*", ignore.case = TRUE)

Arguments

`chapters`	a numeric vector of chapters to search within
`types`	a sub-vector of c('Example','Problem')
`numbers`	a numeric vector of problem numbers
`pattern`	a pattern to use for regular expression matching against the name of the data frame.
`ignore.case`	should case be ignored when matching pattern?
`...`	values for any of `chapters`, `types`, or `pattern`. Which is meant will be inferred from the type of object supplied. This allows users to specify these values in any order and without naming.
