Dear all; I am searching for a way to extract wind direction and speed from a wind rose plot. I have a graph and I want to make a dataframe of 5 years with hourly intervals.
> start_date <- as.POSIXct("2019-01-01 00:00:00") > end_date <- as.POSIXct("2023-12-31 23:00:00") > time_sequence <- seq(from = start_date, to = end_date, by = "hour") > df <- data.frame( year = as.integer(format(time_sequence, "%Y")), month = as.integer(format(time_sequence, "%m")), day = as.integer(format(time_sequence, "%d")), hour = as.integer(format(time_sequence, "%H")) ) > head(df) year month day hour 1 2019 1 1 0 2 2019 1 1 1 3 2019 1 1 2 4 2019 1 1 3 5 2019 1 1 4 6 2019 1 1 5 And I want to add 2 more cols to this dataframe as Wind_Dir and Wind_Speed that the data extracted from the plot by analyzing it. Is there any library to do this? or any function to write for this purpose? I would be more than happy if you please help me to do this. Sincerely -- Best Regards Javad Bayat M.Sc.
