This allows slicing the data even if annotations are missing in some cases:
> d = data.frame(matrix(1:9, nrow = 3))
> annot =
data.frame(
row.names = colnames(d),
A = 1:3,
B = c("A", NA, NA),
C = c(1, NA, NA),
D = factor(c("A", NA, NA))
)
> pheatmap::pheatmap(d, annotation_col = annot)
# this would fail before:
> pheatmap::pheatmap(d[,-1], annotation_col = annot)
