Create heat map

Description

Function for a simple heat map with custom limits in base r plotting. The function is a wrapper for the image function

Usage

heatGrid(
  mat = NULL,
  xrange = NULL,
  yrange = NULL,
  xlimit = NULL,
  ylimit = NULL,
  colramp = topo.colors(200),
  maketicks = T,
  xticks = NULL,
  yticks = NULL,
  makebox = T,
  axislwd = 0.5,
  locut = NULL,
  hicut = NULL,
  nacut = F,
  axisvars = NULL,
  ...
)

pkHeatmap(
  mat = NULL,
  xrange = NULL,
  yrange = NULL,
  xlimit = NULL,
  ylimit = NULL,
  colramp = topo.colors(200),
  maketicks = T,
  xticks = NULL,
  yticks = NULL,
  makebox = T,
  axislwd = 0.5,
  locut = NULL,
  hicut = NULL,
  nacut = F,
  axisvars = NULL,
  ...
)

Arguments

`mat`	matrix with values to create heatmap for
`xrange`	the x range in which to plot the grid (vector length 2)
`yrange`	the y range in which to plot the grid (vector length 2)
`xlimit`	the x limits of the plot (vector length 2)
`ylimit`	the y limits of the plot (vector length 2)
`colramp`	the colors to use for plotting (vector)
`maketicks`	draw simple x,y axes (logical).
`xticks`	position of xticks, defaults to `pretty`
`yticks`	posiition of yticks, defaults to `pretty`
`makebox`	draw box line around plot (logical)
`axislwd`	linewidth to use for ticks and box (numeric)
`locut`	low threshold on raster values (numeric)
`hicut`	high threshold on raster values (numeric)
`nacut`	values outside cutrange are set to NA instead of cut value (logical)
`axisvars`	list with additional arguments to `axis` (named list, not including `side`,`at` or `lwd`)
`...`	other parameters passed to `image` function
