Helper functions in gWidgetsWWW

Description

These functions are simple convenience functions.

Details

The function escapeHTML converts HTML, such as $<$ into a corresponding entity. The reverse is done unescapeURL, so named as such encoding is typically done in URLs.

The function asURL simply adds the class URL to a character. This allows gWidgetsWWW to identify local URLs that are not prefaced with http://.

The function String creates an object of class String. This class treats a character string as a vector of letters. (That is, "abc" is c("a","b","c").) The method c can be used to combine strings. The more natural (in some way, but not every way) + method can also be used to join strings. This is the primary convenience of this class. Otherwise, the [ method is useful for string extraction. The length method is an alternative to nchar.
