First I tried to define the column as date format with:
data_date <-data[as.Date(data_date$Timestamp)<=as.Date("2017-06-15"),]
Then I tried to aggregate as followed:
data_date_sum <- aggregate(data_date$Timestamp, on = "days", k=1,
by=list(cut(as.Date(data_date$Date))), FUN=sum)
R responds:
Error in as.Date.default(data_date$Date) :
do not know how to convert 'data_date$Date' to class ?Date?
I read serveral post, but no other fits to my format.
