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.
Firefox 3.5+.
Edit->Preferences->Tabs->Open new windows in a new tab instead, AND
Enter "about:config" as the URL->'Here be dragons' OK->browser.link.open_newwindow->Set to 1
Now, for general browsing, ctrl-click to open links in a new tab.
Internet Explorer
Tools->Internet Options->Tab Settings->Open links from other programs in->The current tab
Safari
Preferences->General->Open links from Applications->In a new tab in the current window
However, a new tab is created for each help()
. Perhaps a Safari extension is available.
Chrome (including v10) and Chromium
We haven't found a way to stop a new tab for each help()
.
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.
Nothing.
