Not a bug since ?heatmap has a "main" argument. Thus,

heatmap(..., mai = c(1,2,3,4))

is actually interpretted as

heatmap(..., main = c(1,2,3,4))

due to R's partial matching of the argument list. You should try:

pdf()
par(mai = c(1,2,3,4))
heatmap(...)
dev.off()

Hopefully I've assessed this correctly.

HTH,
