Description Usage Arguments Details Value References See Also Examples

View source: R/learn.R

Description

Displays help for the known unknowns saved by unk().

Usage

1
learn(pkgs=NULL,relearn=FALSE,fnam = path.expand("~/.knowns.Rdata"))

Arguments

pkgs

A character vector of package names. NULL means all known unknowns from any package unk() has been passed.

relearn

Reread the manual pages again, even though you already learn()-ed them.

fnam

Same as fnam in unk()

Details

help() is called on each function name. Press ENTER for the next function. ~/.knowns.Rdata is updated to "learn()-ed" status as each function's help page is displayed. Run unk() afterwards when you know them.

We recommend you set options(help_type="html") so that help is displayed in your internet browser. It may be convenient to resize the browser to fill most of your screen, with the R prompt shrunk and non-overlapping with the browser. It is then easier to put focus back the R prompt (to press ENTER) after you have clicked the browser to scroll or follow links.

If you find mutiple windows, or multiple tabs being opened in your browser, you can try the following options.

If you know how to make Safari or Chrome use the current tab for external applications, like Firefox and IE, please let maintainer("unknownR") know so this text may be updated. Thank you.

Value

Nothing.
