The dialogues provide the user with an interface to perform simple and more advanced searches of the R Help pages via the RSiteSearch functionality.
It is possible to perform multiple searches. One can specify up to
9 search terms separated either by "|" (vertical bars, to obtain the
union of results) or "&" (ampersands, to obtain the intersection).
One may use only one type of separating operator per search. For example,
enter in the search box newey west | newey-west | neweywest
or
newey west & newey-west & neweywest
, but not
newey west | newey-west & neweywest
.
Note that findFn()
does not simply search for character strings.
For example, findFn()
may find less results for
differential equation
than for differential equations
.
In such cases you can perform multiple searches as described in the
previous paragraph (differential equation | differential equations
).
For more on this issue see vignette("sos", package="sos")
.
Also note that findFn()
performs the searches on-line, via
Jonathan Baron's R Site Search [1]. Depending on how generic the
search term is (for example, correlation
) and the quality of the
internet connection, it may take from a couple of seconds up to several
minutes to complete the search and display the results.
