This is exactly what I requested, thank you!! However I do actually have several columns in my data sheet where I need to do the same thing, then how do I come about that?
Look at na.approx() in package zoo. Best, Z
e.g. yr<-c(rep(2000,14)) doy<-c(16:29) dat1<-c(3.2,NA,NA,NA,NA,NA,NA,5.1,NA,NA,NA,NA,NA,4.6) dat2<-c(2.2,NA,NA,NA,NA,NA,NA,6.1,NA,NA,NA,NA,NA,4.2) dat3<-c(3.4,NA,NA,NA,NA,NA,NA,4.1,NA,NA,NA,NA,NA,4.7) ta<-cbind(yr,doy,dat1,dat2,dat3) [[alternative HTML version deleted]]
