Here is my code for heatmap3:
colour_palette <- colorRampPalette(c("#F0F0F0", "#DB5634"))(50)
heatmap3(correlation_matrix, col = colour_palette, scale = "none", sym = TRUE, margins = c(9, 9))
and for pheatmap:
pheatmap::pheatmap(mat = correlation_matrix, color = colorRampPalette(c("white","gray", "#FFADAD", "#FF7070", "#FF0000"))(100))
Why are the dendrograms different? Thanks!
