Apply Rolling Median Filter — filter_rollmedian • aniprocess

Applies a rolling median filter to a numeric vector using data.table::frollmedian().

Usage

filter_rollmedian(
  x,
  window_width = 5,
  min_obs = 1,
  align = c("right", "left", "center")
)

Arguments

x: Numeric vector to filter.
window_width: Integer specifying window size for the rolling calculation.
min_obs: Minimum number of non-NA values required in the window. Positions with fewer non-NA values return NA. Defaults to 1.
align: Window alignment. One of "right" (default), "left", or "center".

Value

Filtered numeric vector, same length as x.

Details

Edge handling matches filter_rollmean(): partial windows at the edges for align = "right"/"left"; NA at the edges for align = "center".
