Subset a HeatmapList object

Subset a HeatmapList object

# S3 method for HeatmapList
[(x, i, j)

Arguments

x

A HeatmapList-class object
i

row indices
j

column indices

Details

If the heatmap list is horizontal, i is the row indices and j corresponds to heatmap names and single annotation names. and if the heatlist is vertical, i corresponds to heatmap/annotation names and j is the column indices.

Examples

ht_list = Heatmap(matrix(rnorm(100), 10), name = "rnorm") +
  rowAnnotation(foo = 1:10, bar = anno_points(10:1)) +
  Heatmap(matrix(runif(100), 10), name = "runif")
summary(ht_list[1:5, ])
#> A horizontal heamtap list with 3 heatmap/annotations.
#>   rnorm: a matrix with 5 rows and 10 columns
#>   heatmap_annotation_3: a list of 2 annotations
#>     foo:   a simple annotation.
#>     bar:   a complex annotation.
#>   runif: a matrix with 5 rows and 10 columns
