Joao,
I can't reproduce your results. Try:
str(A)
When I read in the data frame A, I see
> str(A)
'data.frame': 10 obs. of 4 variables:
$ date: int 2006070100 2006070101 2006070102 2006070103 2006070104
2006070105 2006070106 2006070107 2006070108 2006070109
$ my1 : int 1244 1221 1214 1194 1182 1178 1176 1173 1179 1246
$ my2 : int 61 60 60 59 58 58 58 58 58 61
$ my3 : int 62 60 60 59 58 58 58 58 59 62
> temp <- as.Date(A$date, format="%Y%m%d%H")
Error in as.Date.default(A$date, format = "%Y%m%d%H") :
do not know how to convert 'A$date' to class "Date"
Which is a tip off that you need to force date to be a character, either at
read.table time or by doing:
> temp <- as.Date(as.character(A$date), format="%Y%m%d%H")
> temp
[1] "2006-07-01" "2006-07-01" "2006-07-01" "2006-07-01" "2006-07-01"
[6] "2006-07-01" "2006-07-01" "2006-07-01" "2006-07-01" "2006-07-01"
