.capture_promptAny: Internal functions used by reprompt

Description

Internal functions used by reprompt.

Usage

.capture_promptAny(fnam, type, package, final, ..., methods)
.capture_installed_help(fnam, type = NULL, package = NULL, suffix = NULL)

Arguments

fnam

extended name of the object, such as "fun", "gen-methods", "S4cl-class" or "pkname-package", see details.

final

if TRUE, put dummy title and description to make the file immediately usable.

...

further arguments to pass on to the prompt function(s).

methods

methods to consider, used only when describing S4 methods.

type

type of documentation, such as "methods" and "class", see Details.

package

the package where to look for objects or documentation, useful if more objects of the same name exist.

suffix

a character string to be appended to fnam to obtain the complete name of the help topic, e.g. "-class", "-method".

Value

an Rd object on success or a try-error object otherwise

Details

These functions are used internally by reprompt. It falls back to them when only when the user has not supplied an Rd file in the call.

Note that for editing it is preferable to use the source Rd files (when available), since some hard coded information in the installed help may have been produced by more elaborated code in the Rd sources, most notably Sweave expressions.

.capture_promptAny is used to generate documentation when none has been supplied by the user or loaded in the session. .capture_promptAny parses fnam to obtain the name of the object and the type of the required documentation (function, methods, class), then generates it. Currently this is done with the built in functions of the promptXXX family.

.capture_installed_help does exactly that --- it captures the currently installed requested help topic. This function needs clean up. It was originally written at a time when both the old and new help formats where co-existing.
