I have a dataset in a .csv for Pacific Decadal Oscillation (PDO) that has the date in the format yyyymm. For example January of 1980 would be 198001. How would I go about getting r to read this.
I have tried
PDO$date1<-as.POSIXct(PDO$Date, format= "%Y%m")
and
as.Date(as.character(PDO$Date), format='%Y%m')
With as.POSIXct it says that orign must be supplied and with as.Date it returns NA.
Thanks for the help.
