thank you!

both solutions
1.) maleOver40 <- subset(d, sex %in% c("m","M") & age > 40)
2.) maleOver40 <- d[(d$sex == "m" | d$sex == "M") & d$age > 40,]

"I have seen things you people wouldn't believe.
Attack-ships  on fire off the shoulder of Orion.
I watched seabeams glitter in the dark near the 
Tannhauser gate.
All  those  moments  will  be lost in time like
tears in rain. Time to die."              (Roy)
