mising arguments in mongo.Rd

[ralmond]

The options argument to the $argument() function, although documented in the vignette, is missing from the reference page for mongo().

> args(mongo()$aggregate)
function (pipeline = "{}", options = "{\"allowDiskUse\":true}", 
    handler = NULL, pagesize = 1000, iterate = FALSE) 

Similarly, the filters argument is missing in the documentation for $update()

> args(mongo()$update)
function (query, update = "{\"$set\":{}}", filters = NULL, upsert = FALSE, 
    multiple = FALSE)
