Details

If adding the row summary to a horizontally oriented heatmap, the summary will be based on the right-most heatmap if side is "right" and based on the left heatmap if side is "left" unless a "heatmap_name" is specified. The heatmap_name should match the "pname" argument given to a previously added heatmap.

The row summary is based on specific columns if a "groups" argument is given. The groups argument can either be a vector of group assignments for each row, the "pname" for an existing set of groups incorporated into the plot using add_col_groups, add_col_annotation, add_col_clusters, or add_col_clustering. If groups is set to TRUE, then the function will use an existing set of column groups added to the plot.

Examples

mat <- matrix(rnorm(20), ncol = 5, nrow = 4)  
hm1 <- iheatmap(mat) %>% add_row_summary()
hm2 <- iheatmap(mat) %>% add_row_summary(groups = c("A","A","B","B","B"))

# Print heatmap if interactive session 
if (interactive()) hm1
if (interactive()) hm2
