port on which the server should run (both help and SciViews). By default, it is port 8888. Note that this server runs only locally and can only serve requests from 127.0.0.1 (because communication is not crypted). |
A number with the port of the HTTP server.

named arguments specifying options to set or change. |
An environment that contains the whole configuration is returned invisibly.
Possible named arguments (with their default values) are: prompt = ":> "
for the server prompt, continue = ":+ " for the continuation prompt when
multiline instructions are send, code = "" for current partial code in
multiline mode, last = "" for a string to add at the end of each
evaluation, echo = FALSE to echo commands at the R console or terminal,
multiline = TRUE to allow multiline mode, bare = TRUE a bare mode that
inactivates all other options (the server is always started in bare mode).

Turn the default R help HTTP server into a RJSONp SciViews server (while still serving help pages, of course).
