compute nanmedian

compute.nanmedian( arr[, opts] )

Computes the median of an array ignoring non-numeric values.

var data = [ 2, null, 4, 2, NaN, 7, 3 ];

var median = compute.nanmedian( data );
// returns 3

If the input array is already sorted in ascending order, set the sorted option to true.

var data = [ 2, null, 2, 3, NaN, 4, 7 ];

var median = compute.nanmedian( data, {
	'sorted': true	
});
// returns 3

For object arrays, provide an accessor function for accessing array values

var data = [
	[1,2],
	[2,null],
	[3,4],
	[4,2],
	[5,NaN],
	[6,7],
	[7,3]
];

function getValue( d ) {
	return d[ 1 ];
}

var median = compute.nanmedian( data, {
	'accessor': getValue
});
// returns 3
