plot_heathour {AeRobiology}

Plotting hourly patterns with heatplot

Description

Function to plot pollen data expressed in concentrations with time resolution higher than 1 day (e.g. hourly, bi-hourly concentrations). As heatplot.

Usage

plot_heathour(data, locations = FALSE, low.col = "blue",
  mid.col = "white", high.col = "red")

Arguments

data

A data.frame object with the structure long. Where the first two columns are factors indicating the pollen and the location. The 3 and 4 columns are POSIXct, showing the hour. Where the third column is the beguinning of the concentration from and the fourth column is the end time of the concentrtion data to. The fifth column shows the concentrations of the different pollen types as numeric. Please see the example 3-hourly data from the automatic pollen monitor BAA500 from Munich and Viechtach in Bavaria (Germany) data("POMO_pollen"), supplied by ePIN Network supported by the Bavarian Government.

locations

A logical object with the specification if the different locations will be displayed in the plot. Argument only used when result == "plot". By default, locations = FALSE.

low.col

A character object with the specification of the color of the lowest value for the scale. By default, low.col = "blue".

mid.col

A character object with the specification of the color of the medium value for the scale. By default, mid.col = "white".

high.col

A character object with the specification object with the specification of the color of the highest value for the scale. By default, high.col = "red".

Value

The function returns an object or a list of objects of class ggplot2.
