I just did this the other day. Funny you should ask. It finds the
mode of each row of a matrix called Pbest.
Pbest.p <- apply(Pbest,1,function(x)
x[which.max(as.vector(table(x)))][1])
So to get the mode of a vector v1, the following should work (but I
haven't tried it):
v1[which.max(as.vector(table(v1)))][1]
