Hello and thanks for helping. #some data L3 <- LETTERS[1:3] dat1 <- data.frame(cbind(x=1, y=rep(1:3,2), fac=sample(L3, 6, replace=TRUE)))
#When x==1 and y==1 I want to replace the 1 values with NA #I can select the rows I want: dat2<-subset(dat1,x==1 & y==1) #replace the 1 with NA dat2$x<-rep(NA,nrow(dat2) dat2$y<-rep(NA,nrow(dat2) #select the other rows and rbind everything back together #This is where I get stuck #The end dataframe will look something like: x y fac NA NA B NA NA A 1 2 C 1 3 C 1 2 C 1 3 A #Is there a better way to do this where I do not need to subset perhaps using lapply?
