## S3 method for class 'numeric'
extract_seasonality(.x, .freq = 12, .method = "stl",
  .part = "seasonal")

`.x`	numeric vector
`.freq`	frequency for time series
`.method`	method/methods to extract seasonality; could be "stl" (default), "additive", "multiplicative"
`.part`	parts of decomposition to keep: "seasonal" (default), "trend", "remainder"

data frame with .part parts of .method decompositions

x <- rep(c(1:6, 6:1), 10)
seasonalities <- extract_seasonality(x, .freq = 12, .method = c("stl", "additive"))
head(seasonalities)
