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.
