Function has partly been taken from
getForm function. Generally, a feed
query is a string built up as follows:
?&&...&
By specifying a feed url and parameter--value pairs
(as list) we can easily generate a feed query in R.
Usage
feedquery(url, params)
Arguments
url
character specifying feed url
params
list which contains feed parameters, e.g.
list(param1="value1", param2="value2")
