More combination to expand grid function in R

I have data as

subtype <- c("ar","sub")
height <- c("0","1")

I am using expand.grid(subtype,height) but I get 

Var1    Var2
ar        0
sub       0
ar        1
sub       1

I need

Var1    Var2
ar       0
sub      1
ar       1
sub      0
ar       0
sub      0
ar       1
sub      1

I think this gives the data you want (just in a different order)

cbind.data.frame(Var1=subtype , Var2=c(t(as.matrix(expand.grid(height,height)))))

#   Var1 Var2
# 1   ar    0
# 2  sub    0
# 3   ar    1
# 4  sub    0
# 5   ar    0
# 6  sub    1
# 7   ar    1
# 8  sub    1
