apci.plot.heatmap {APCI}  R Documentation 
Plot the heatmap for APCI model
Description
Plot the heatmap to visualize cohort effects estimated by APCI model.
Usage
apci.plot.heatmap(
model,
age,
period,
color_map = NULL,
color_scale = NULL,
quantile = NULL,
...
)
Arguments
model 
A list recording the results from function 
age 
An object of class character representing the age group index taking on a small number of distinct values in the data. Usually, the vector should be converted to a factor (or the terms of "category" and "enumerated type"). 
period 
An object of class character, similar to the argument of age, representing the time period index in the data. 
color_map 
A vector, representing the color palettes to
be used in the figure. The default setting is greys if color_map is

color_scale 
A vector including two numbers indicating the limit of the values to be plotted. The first number is the minimum value to be visualized and the second is the maximum value to be visualized. If NULL, the algorithm will automatically select the limits from the data (estimation results) to set up the scale. 
quantile 
A number valued between 0 and 1, representing the
desirable percentiles to be used in visualizing the data or model.
If 
... 
Additional arguments to be passed to the function. 
Value
A heatmap visualizing cohort effects estimated by APCI model.
