Hello Ben, First of all thanks for the reply,and sorry because I haven't replied early. In this time I find another form to create the "my time", like this:
bbrass = scan("C:/Program Files/R/data PTIN/bbrass_client_2471_pool_72644_percent_in_use_500_NA.dat") regts.start = ISOdatetime(2006, 7, 1, hour=0, min=0, sec=0, tz="GMT") #2006 07 01 00 regts.end = ISOdatetime(2006, 7, 22, hour=2, min=0, sec=0, tz="GMT") #2006 07 22 02 regts.zoo <- zooreg(bbrass, regts.start, regts.end, deltat=3600) summary(regts.zoo) Index regts.zoo Min. :2006-07-01 00:00:00 Min. :48 1st Qu.:2006-07-06 06:15:00 1st Qu.:58 Median :2006-07-11 12:30:00 Median :62 Mean :2006-07-11 12:30:00 Mean :65 3rd Qu.:2006-07-16 18:45:00 3rd Qu.:74 Max. :2006-07-22 01:00:00 Max. :81 NA's :40 Then I create a time serie and the REGUL fuction works fine. About your sugestions: (1) R version In using R version 2.5.1 (2007-06-27) (2) meaningful subject line would be nice Sorry, but this was my first message to the list and only after I post I realize that the subject was empty.
