Dear all,
I am trying to identify the days absent in a vector so as to be able to
display missing data in the graphics in .It should be done automatically
since the graphics will be generated for different periods of the year.
I have been trying to do a function below but it did not work. I really
appreciate any help
ordados <- function(datas,var)
{
ind <- !datas %in% var # find the missing date in var
miss <- datas[ind]
mat <- matrix(NA,length(miss),length(miss)) #insert NA in the missing date
mat[,1]<-miss
jundado <- rbind (mat,var)
jundado <- jundado[order(jundado[,1]),] # sort by dates
}
For instance:
If I have the vector below:
2009-12-01 26.8
2009-12-03 27.9
2009-12-04 25.6
2009-12-05 20.8
2009-12-08 20.8
I will need a result like this one
2009-12-01 26.8
2009-12-02 NA
2009-12-03 27.9
2009-12-04 25.6
2009-12-05 20.8
2009-12-06 NA
2009-12-07 NA
2009-12-08 20.8
Bye and Best Regards
