Re: [R] Simple question on binning data
Wow! This definitely contributed to my evening.

[R] Simple question on binning data
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?

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. george5000 wrote: Hello everyone, I have a data set, and I need to bin my data using a bin width of say g(n).
