promptPackage {utils} | R Documentation |
Generates a shell of documentation for an installed or source package.
promptPackage(package, lib.loc = NULL, filename = NULL,
name = NULL, final = FALSE)
package |
the name of an installed or source package to be documented. |
lib.loc |
a character vector describing the location of R
library trees to search through, or |
filename |
usually, a connection or a character string giving the
name of the file to which the documentation shell should be written.
The default corresponds to a file whose name is |
name |
a character string specifying the name of the help topic,
typically of the form |
final |
a logical value indicating whether to attempt to create a usable version of the help topic, rather than just a shell. |
Unless filename
is NA
, a documentation shell for
package
is written to the file specified by filename
, and
a message about this is given.
If filename
is NA
, a list-style representation of the
documentation shell is created and returned. Writing the shell to a
file amounts to cat(unlist(x), file = filename, sep = "\n")
,
where x
is the list-style representation.
If final
is TRUE
, the generated documentation will not
include the place-holder slots for manual editing, it will be usable
as-is. In most cases a manually edited file is preferable (but
final = TRUE
is certainly less work).
If filename
is NA
, a list-style representation of the
documentation shell. Otherwise, the name of the file written to is
returned invisibly.
