Continuous variable into levels

Hello everyone

I have a variable with about 5000 different values

var1= c(0, 123, 400, .....4988)

I want to convert it into different levels for some comparisons like

if value is between 1-100 do something
else
do other things

Is there any sophisticated way to do that than the following:

var2=cut(var1, br=c(-1,500, 501,1000, 1001,5000))

Thank you

Hi Neha,
I think you're looking for the "cut" function.

Hello Jim

So, you believe the following way is better ?

var2=cut(var1, br=c(-1,500, 501,1000, 1001,5000))

Sorry, it was such an easy question that I didn't even read it
closely. Apparently using hist() is a bit faster. Whether this is
worth it, I don't know.

Hello,

And ?findInterval is faster than hist.

findInterval(x, c(-Inf, 500, 1000, 5000))

Also, before the cut code, the OP wrote


if value is between 1-100 do something


but in the breaks vector there's no 100. I guess this is not important,
though, only the function to bin the data is.

Hope this helps,
