`type`	Averaging method ("uniform" [even], "weighted" [default], or "centered") for creating weights.

Value

Returns vector of weights

Examples

wgts<- filterWgts(0,"uniform")
wgts<- filterWgts(7,"uniform")
wgts<- filterWgts(7,"centered")
wgts<- filterWgts(7,"weighted")
x <- 1:100
filter(x, filterWgts(7,"weighted"), sides=1)
