Heatmap Plot for Time Series

Heatmap plot for time series object by it periodicity (currently support only daily, weekly, monthly and quarterly frequencies)

ts_heatmap(ts.obj, last = NULL, wday = TRUE, color = "Blues",
  title = NULL, padding = TRUE)

Arguments

ts.obj	A univariate time series object of a class "ts", "zoo", "xts", and the data frame family (data.frame, data.table, tbl, tibble, etc.) with a Date column and at least one numeric column. This function support time series objects with a daily, weekly, monthly and quarterly frequencies
last	An integer (optional), set a subset using only the last observations in the series
wday	An boolean, provides a weekday veiw for daily data (relevent only for objects with dates such as xts, zoo, data.frame, etc.)
color	A character, setting the color palette of the heatmap. Corresponding to any of the RColorBrewer palette or any other arguments of the `col_numeric` function. By default using the "Blues" palette
title	A character (optional), set the plot title
padding	A boolean, if TRUE will add to the heatmap spaces between the observations
