d,	optional (default: movies), dataset to get a random subset from.

Value

A data frame with a random numer of rows

Examples

##Given the same student ID
##the same data set is returned
d1 = getRandomData("b1234567")
d2 = getRandomData("b1234567")
identical(d1, d2)
##Different IDs get different data
d3 = getRandomData("b1234568")
identical(d1, d3)
