Subject: breaks
Dear R People:
I have a question about a "sorting" problem, please.
I have a vector xx:
> xx
[1] -2.0 1.4 -1.2 -2.2 0.4 1.5 -2.2 0.2 -0.4 -0.9
and a vector of breaks:
> xx.y
[1] -2.2000000 -0.9666667 0.2666667 1.5000000
I want to produce another vector z which contains the number of the class
that each data point is in.
for instance, xx[1] is between xx.y[1] and xx.y[2], so z[1] == 1
this can be accomplished via loops, but I was wondering if there is a more
efficient method, please.
By the way, eventually, there will be many more data points and more
classes.
thank you for any help!
sincerely,
Erin Hodgess
