Hello,
Is there a function that returns the number of the "bin" (or
quantile, or percentile etc. etc.) that a value of a variable may belong to?
Tor example:
breaks<-hist(variable, 18, plot=FALSE)
If the following breaks are
5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85
the boundaries of successive bins of a histogram, then value "6"
belongs to the 2nd bin.
Best regards,
Costas
