This function is for internal use. It creates a color scaled bar for heatmap.

Usage

.colorBar(
  z,
  zlim,
  col = heat.colors(12),
  breaks,
  horiz = TRUE,
  ylim = NULL,
  xlim = NULL,
  lwd = 0.5,
  cex.axis = 1,
  ...
)

Arguments

z	matrix of values used to visualize the heatmap
zlim	Limit for the numerical(color) scale, which must be consistent with parameter 'break'.
col	Palette of color to use
breaks	Numerical vector with the breaks used to produce the heatmap
horiz	Whether to the color bar will be horizontal(= TRUE) or vertical(= FALSE)
ylim	User defined limits for y-axis. Depending on the orientation, x- or y-limits may be defined that are different from the z-limits and will reduce the range of colors displayed.
xlim	User defined limits for x-axis
lwd	Line width.
