Dear R users, I have a reproducible data and try to create new variable "clo" is 1 if know variable is equal to "very well" or "fairly well" and getalong is 4 or 5 otherwise it is 0.
rep_data<- read.table(header=TRUE, text=" id1 id2 know getalong 100000016_a1 100000016_a2 very well 4 100000035_a1 100000035_a2 fairly well NA 100000036_a1 100000036_a2 very well 3 100000039_a1 100000039_a2 very well 5 100000067_a1 100000067_a2 very well 5 100000076_a1 100000076_a2 fairly well 5 ") rep_data$clo<- ifelse((rep_data$know==c("fairly well","very well") & rep_data$getalong==c(4,5)),1,0) For sure, something must be wrong, I couldn't find it out. rep_data id1 id2 know getalong clo 100000016_a1 100000016_a2 very well 4 0 100000035_a1 100000035_a2 fairly well NA 0 100000036_a1 100000036_a2 very well 3 0 100000039_a1 100000039_a2 very well 5 0 100000067_a1 100000067_a2 very well 5 0 100000076_a1 100000076_a2 fairly well 5 0 Any help is appreciated..
