Description Usage Arguments Details Value Author(s) References See Also Examples

The repr_paa computes PAA representation from a vector.

1	repr_paa(x, q, func)

`x`	the numeric vector (time series)
`q`	the integer of the length of the "piece"
`func`	the aggregation function. Can be meanC, medianC, sumC, minC or maxC or similar aggregation function

PAA with possibility to use arbitrary aggregation function. The original method uses average as aggregation function.

the numeric vector
