get_colors | R Documentation |
This function returns a vector of colors based on a vector of cluster names. It can be used to automatically assign colors.
get_colors(colors = NULL, clusters)
colors |
A vector of colors. If |
clusters |
A vector of cluster names. |
A named vector where the values are the colors to use for displaying them different clusters. For some use cases, you might have to either change the names or use unname().
## Obtain the necessary data
if (!exists("sce_layer")) sce_layer <- fetch_data("sce_layer")
## Example layer colors with the corresponding names
get_colors(libd_layer_colors, sce_layer$layer_guess)
get_colors(libd_layer_colors, sce_layer$layer_guess_reordered_short)
## Example where colors are assigned automatically
## based on a pre-defined set of colors
get_colors(clusters = sce_layer$kmeans_k7)
## Example where Polychrome::palette36.colors() gets used
get_colors(clusters = letters[seq_len(13)])
## What happens if you have a logical variable with NAs?
set.seed(20240712)
log_var <- sample(c(TRUE, FALSE, NA),
1000,
replace = TRUE,
prob = c(0.3, 0.15, 0.55))
log_var_sorted <- sort_clusters(log_var)
## A color does get assigned to 'NA', but will be overwritten by
## 'na_color' passed to `vis_clus_p()` and related functions.
get_colors(colors = NULL, clusters = log_var_sorted)
