However, I'm going to go way out on a limb here, as I know absolutely
nothing of what you're up to, and suggest that you do NOT need to bin your
data.

Bert is correct. Binning is seldom needed and usually distorts. It is
the statistical equivalent of a former governor from Alaska.

Subject: Re: [R] Simple question on binning data
There would be several people who could help if you gave us a minimal,
reproducible example like the posting guide asks for.
If you have a vector of continuous data, and need to create a
categorical variable (in R, a factor) from that continuous variable,
then ?cut can help you.

Hello everyone,
I have a data set, and I need to bin my data using a bin width of say
g(n).
Would anyone be willing to tell me how to do this in R?
Thanks
