Dear R-Users,
i want to use the function mice of the mice package with data, that
contains dates, but this gives an error
x <- Sys.time()
dat <- data.frame(dates=(1:10)*60*60*24+x, size=rnorm(10))
dat$dates[c(3,7)]<-NA
mice(dat)
Fehler in check.imputationMethod(imputationMethod,
defaultImputationMethod, :
The following functions were not found: mice.impute.
I guess the mice package is not implemented for the POSIXt data class yet.
A workaround could be to build time intervals and use mice with that and
transform it back afterwards. Or is there a more efficient way?
I think you are completely right.
You may want to provide a method for the mice maintainer who will
certainly be happy about your contribution.
Best,
Uwe Ligges
Many thanks if anyone could tell me what i do wrong and what is the
problem here.
best regards
Andreas
