This may be a newbie problem.  I am attempting tor unt the simplex routine from
the boot package.  The example code doesn't find simplex.  What's wrong here?

>      vitx <- c(50, 3, 150, 100)

>      vitz <- c(150, 35, 75, 5)
>      simplex(a=enj, A1=fat, b1=13800, A2=rbind(vitx, vity, vitz), 
+              b2=c(600, 300, 550), maxi=TRUE)
