Hi Experts, This may be simple question, I want to create new variable "seg" and assign values to it based on some conditions satisfied by each observation.
Here is the example: ##Below are the conditions ##if variable x2 gt 0 and x3 gt 200 then seg should take value 1, ##if variable x2 gt 100 and x3 gt 300 then seg should take value 2 ##if variable x2 gt 200 and x3 gt 400 then seg should take value 3 ##if variable x2 gt 300 and x3 gt 500 then seg should take value 4 id <- c(1,2,3,4,5) x2 <- c(200,100,400,500,600) x3 <- c(300,400,500,600,700) dd <- data.frame(id,x2,x3) dd$seg[dd$x2> 0 && dd$x3> 200] <-1 dd$seg[dd$x2> 100 && dd$x3> 300] <-2 dd$seg[dd$x2> 200 && dd$x3> 400] <-3 dd$seg[dd$x2> 300 && dd$x3> 500] <-4 I tried as above but it is not working for me. What is the correct and efficient way to do this.
