Say I have the following data:
house_number<-floor(runif(100, 200, 600)) water_evaluation<-c("No water damage", "Water damage", "Water On", "Water off", "water pipes damaged", "leaking water") water_evaluation_selection<-floor(runif(100, 1,6)) house_info<-data.frame(water_evaluation[water_evaluation_selection], house_number) And, that I only want to pull out the ones with negative water evaluations, i.e. Water damage, water pipes damaged, and leaking water. Should/could I use grep in order to pull the house numbers out of house_info with those negative water evaluations? I guess I want to know the house numbers from house_info where the water evaluation is negative. Is there a way to use grep or another R function in order to acquire that information? Thank you again in advance for any insights. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
