Display a randomly chosen statistical quote.
Usage
statquote(ind = NULL, pattern = NULL, tag = NULL, source = NULL, topic = NULL)
# S3 method for class 'statquote'
print(x, cite = TRUE, width = NULL, ...)
# S3 method for class 'statquote'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)Arguments
- ind
Integer or character. If 'ind' is missing, a random quote is chosen from all quotations. If 'ind' is specified and is an integer, return the ind^th quote. If 'ind' is specified and is character, use it as the 'pattern'.
- pattern
Character string. Quotes are subset to to those which match the pattern in the quote text.
- tag
Character string. Quotes are subset to those matching the specified tag.
- source
Character string. Quotes are subset to those matching the specified source (person).
- topic
Deprecated. Use 'tag' instead. Only kept for backward compatibility.
- x
object of class
'statquote'- cite
logical; should the
citefield be printed?- width
Optional print width parameter
- ...
Other optional arguments, unused here
- row.names

as.data.frame
Value
A character vector containing one quote.
It is of class statquote for which an S3 print method will be invoked, and for which
other methods are available.

#> Without this sort of flexibility, progress in physical science would
