I executed the following steps, “date” column with in a yyyy-dd-mm format and a chr datatype. I converted that column to numeric the created a new “year” column with df$year = as.numeric(format(df$year, “%Y”)). I successfully created the new column but all the values were NAs. Is there a better way?
