+vega.<b>writeConfig</b>(<i>config</i>, <i>key</i>, <i>value</i>[, <i>recurse</i>])

+
+Writes a value to a Vega configuration object. Given a *config* object and a configuration property *key* and *value*, appropriately assign the value to the config object. The *recurse* parameter controls if recursive merging (as opposed to overwriting) is performed: if `false` or undefined, no recursion is performed; if `true` one level of recursive merge is performed; if *recurse* is object-valued, one level of recursive merge is performed for keys that the *recurse* object maps to a truthy value. This method is a helper method used within *mergeConfig*.
