stl does this internally: x <- na.action(as.ts(x))
so stl(x, s.window, na.action = f) is the same as stl(f(as.ts(x)), s.window) e.g. nottem[25] <- NA # nottem is a built in data set in R stl(nottem, "per") # error stl(nottem, "per", na.action = na.contiguous) library(zoo) stl(nottem, "per", na.action = na.locf) stl(nottem, "per", na.action = na.approx) Whether any of these makes sense is another matter.
