Hi,

I have a continuous variable in my dataset with this distribution:

summary(emissions$NOX_gram) Min. 1st Qu. Median Mean 3rd Qu. Max. 0 256 547 15802 1074 50818630

how can I categorize this variable to the levels of extremely high to extremely low, low, high, and medium in R or excel? i need to see for example the highest emission produced by the last category of the household.

thank you for the help

I tried cut function in r but the result was not what I expected, in my data the 3rd Qu. is lower than the Mean.
