[Pritam]

Hi ,
I am new to R.
So I would require a bit of your help.
I have a dataset Of College Admission_CSV in which I have a Column call gre that is to be classified as follows:

0-440	Low
440-580	Medium
580+	High

I have also attached in Attachment the dataset & the requirement.

nirgrahamuk can you please help me with the code how to accomplish this in R . Should I use if else?

Anyone can you please help me with the code?

You could do something like this

library(dplyr)

your_dataframe_name <- your_dataframe_name %>% 
    mutate(gre_class = case_when(
        gre < 440 ~ "Low",
        gre > 440 & gre < 580 ~ "Medium",
        gre > 580 ~ "High"
    ))

If you need more specific help, please provide a proper REPRoducible EXample (reprex) illustrating your issue.

This is not an R question, this question could be posed for any programming,statistical analysis tool, even spreadsheet....
That aside,.. what specifically are the elements you want help with ?
percentages?
plotting ?
