Im stuck in a simple problem.
I need to run something like this
refreshg$ff=ifelse(refreshg$hh %in% listhh,0,1)
So, if the value from listhh exists in refreshg$hh, resfresh$ff will be 0. Anything else must be equal to 1.
However, I need to modify this in order to be applied to the first occurrence.
I mean, I detected some duplicates of hh in resreshg, so when I count the cases I see some hh vales that are repeated, some ff values with a count of 2 or more.
I just can't specify the rule of just run the code above over the first, and only first, occurrence.
I tried to perform this using dplyr, and I failed.
library(tidyverse) oo=c(1,2,3,4,5,6,7,8,9,10,11,12,13) hh=c(1,2,3,4,10,6,4,8,9,10,1,6,6) data=data.frame(oo,hh) listhh=c(1,4,6,8,10) data$ff=ifelse(data$hh %in% listhh,1,0) data data$desired=c(1,0,0,1,1,1,0,1,0,0,0,0,0) data
Thanks for your work and time
