How can I merge data frame df and "tem" shown below by filling the
head of "tem" with missing values?
does
c(rep(NA, nrow(df) - length(tem)), tem)
help?
a<- rnorm(1825, 20)
b<- rnorm(1825, 30)
date<-seq(as.Date("2000/1/1"), by = "day", length.out = 1825)
df<-data.frame(date,a,b)
tem<- rpois(1095, lambda=21)
Thanks
