Dear All:
I'd like to know how to sort and then index a vector of floats by several levels in R.
For example
x<-rnorm(100) MyLevels<-quantile(x,probs=c(0,.5,1)) MyLevels
0% 50% 100% -2.11978442 -0.03770613 2.00186397
next i want to replace each x[i] in x by 1,2,3 or 4 depending on which quantile that x[i] falls. How do I do that in a "vector" fashion?
I think rank() is the function you're looking for.
Cheers
