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:

par(mai = c(1,2,3,4))

Hopefully I've assessed this correctly.



P.S. See the posting guide regarding attachments to the list.
