In QuantTools: Enhanced Quantitative Trading Modelling

Description

Multi Dimensional Heat Map

Usage

multi_heatmap(x, pars, value, col_neg = c("darkblue", "lightblue"),
  col_pos = c("yellow", "darkgreen"), peak_value = x[, max(abs(get(value)),
  na.rm = T)])

Arguments

x	data.table object
pars	names of parameters. Parameters combinations must be unique. To specify x and y axes use list( x = ..., y = ... ).
value	name of value parameter
col_pos, col_neg	used to generate gradient
peak_value	normalization value

Details

Plots multi dimensional heatmap. Axes drawn automatically by layers. Inner axes are most frequent and outer axes are less frequent.
