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)
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. |
The block annotation is used for representing slices. The length of all arguments should be 1 or the number of slices.
An annotation function which can be used in HeatmapAnnotation
.
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)
