Block annotation

anno_block(gp = gpar(), labels = NULL, labels_gp = gpar(), labels_rot = ifelse(which == "row", 90, 0),
    which = c("column", "row"), width = NULL, height = NULL)

Arguments

gp	Graphic parameters.
labels	Labels put on blocks.
labels_gp	Graphic parameters for labels.
labels_rot	Rotation for labels.
which	Is it a row annotation or a column annotation?
width	Width of the annotation. The value should be an absolute unit. Width is not allowed to be set for column annotation.
height	Height of the annotation. The value should be an absolute unit. Height is not allowed to be set for row annotation.

Examples

Heatmap(matrix(rnorm(100), 10),
    top_annotation = HeatmapAnnotation(foo = anno_block(gp = gpar(fill = 2:4),
        labels = c("group1", "group2", "group3"), labels_gp = gpar(col = "white"))),
    column_km = 3,
    left_annotation = rowAnnotation(foo = anno_block(gp = gpar(fill = 2:4),
        labels = c("group1", "group2", "group3"), labels_gp = gpar(col = "white"))),
    row_km = 3)
