insper_heatmap(
  data,
  show_values = FALSE,
  value_color = "white",
  value_size = 3,
  palette = "vermelho_turquesa",
  ...
)

Arguments

data

show_values

Logical. If TRUE, prints values on the tiles. Default is FALSE.

value_color

Examples

if (FALSE) { # has_insper_fonts()
# From a correlation matrix
cor_mat <- cor(mtcars[, 1:4])
insper_heatmap(cor_mat)

# Print values on the tiles
insper_heatmap(cor_mat, show_values = TRUE)

# Another diverging palette
insper_heatmap(cor_mat, palette = "roxo_verde")
