Duplicated date values aren't duplicates
Dear list,
I just had a function (as.ltraj in Adehabitat) give me the following error:
"Error in as.ltraj(xy, id, date = da) : non unique dates for a given burst"
I checked my dates and got the following:
> dupes<-mydata$DateTime[duplicated(mydata$DateTime)]
> dupes
[1] (07/30/02 00:00:00) (08/06/03 17:45:00)
Is there a reason different dates would come up as duplicate

ESRI shape file import and time-space models
Dear R user,
I am running R under Windows 2000.
I am looking for a routine for importing
- shape files (ESRI) into R
- dbase files (FOXPRO) into R
and I am looking for time-space models for description and prediction of
Bernoulli-, Binomial- and Poissonvaraibles.
Thank's a lot for a reply.
Sincerely yours,
