compute nanquantiles

compute.nanquantiles( arr, num[, opts] )

Computes quantiles for an array ignoring non-numeric values. num specifies the number of quantiles to compute.

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

var arr = compute.nanquantiles( data, 3 );

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

var opts = {
	'sorted': true
};

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

var arr = compute.nanquantiles( data, 2, opts );
// returns [ 2, 3, 7 ]

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

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

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

var opts = {
	'sorted': true,
	'accessor': getValue
};

var arr = compute.nanquantiles( data, 2, opts );
// returns [2, 3, 7 ]
