Hi all, I am trying to use the if else statement and create two new columns based on the existing two columns. Below please find my sample data,
dat1 <-read.table(text="ID a b c d A private couple 25 35 B private single 24 38 C none single 28 32 E none none 20 36 ",header=TRUE,stringsAsFactors=F) dat1$z <- "Zero" dat1$y <- 0 if a is "private" and (b is either "couple" rr "single" then z value = a's value and y value = c's value if a is "none" and ( b is either couple of single then z= private then z value =b's value qnd y value= d's value else z value= Zero and y value=0 the desired out put looks like ID a b c d z y 1 A private couple 25 35 private 25 2 B private single 24 38 private 24 3 C none single 28 32 single 32 4 E none none 20 36 Zero 0 my attempt if (dat1$a =="private" & (dat1$b =="couple"| dat1$b =="single")) { dat1$z <- dat1$a dat1$y <- dat1$c } else if (dat1$a =="none" & (dat1$b =="couple"| dat1$b =="single")) { dat1$z <- dat1$b dat1$y <- dat1$c } else { default value} did not wok, how could I fix this?
