corrplot (version 0.84)

colorlegend: Draw color legend.

Description

Draw color legend.

Usage

colorlegend(colbar, labels, at = NULL, xlim = c(0, 1), ylim = c(0, 1),
  vertical = TRUE, ratio.colbar = 0.4, lim.segment = "auto",
  align = c("c", "l", "r"), addlabels = TRUE, ...)

Arguments

colbar

Vector, color of colbar.

labels

Vector, numeric or character to be written.

at

Numeric vector (quantile), the position to put labels. See examples for details.

xlim

See in plot

ylim

See in plot

vertical

Logical, whether the colorlegend is vertical or horizon.

ratio.colbar

The width ratio of colorbar to the total colorlegend (including colorbar, segments and labels).

lim.segment

Vector (quantile) of length 2, the elements should be in [0,1], giving segments coordinates ranges. If the value is NULL or "auto", then the ranges are derived automatically.

align

Character, alignment type of labels, "l" means left, "c" means center and "r" right.

addlabels

Logical, whether add text label or not.

Examples

# NOT RUN {
par(mar = rep(0,4))
plot(0,xlim = c(0,6), ylim = c(-0.5,1.2), type = "n")

colorlegend(rainbow(100), 0:9)

colorlegend(heat.colors(100), LETTERS[1:12], xlim = c(1,2))

colorlegend(terrain.colors(100), 0:9, ratio.colbar = 0.6,
            lim.segment = c(0,0.6), xlim = c(2,3), align = "l")

colorlegend(topo.colors(100), 0:9, lim.segment = c(0,0.6),
            xlim = c(3,4), align = "l", offset = 0)

colorlegend(cm.colors(100),1:5, xlim = c(4,5))

colorlegend(sample(rainbow(12)), labels = LETTERS[1:12],
            at = seq(0.05, 0.95, len = 12), xlim = c(5,6), align = "r")

colorlegend(colbar = grey(1:100 / 100), 1:10, col = "red", align = "l",
            xlim = c(0, 6), ylim = c(-0.5,-0.1), vertical = FALSE)

colorlegend(sample(rainbow(12)),
            labels = LETTERS[1:12], at = seq(0.05, 0.95, len = 12),
            xlim = c(0, 6), ylim = c(1.1, 1.2), vertical = FALSE)
