I received this error with no chart showing after doing the filter for the second half of 2008. "Warning message: Removed 5740 row(s) containing missing values (geom_path)." I rechecked the code but couldn't figure it out.

Hi Mohamed I have the same error and I didn't figure it So I Rechecked the whole script and compared it with the script in the resources my error was here spx_ftse_00_10$Date <- as.Date(spx_ftse_00_10$Date, format = "%m/%d/%y") when I checked the values of date I noticed that all the years become 2020 not started from 2000 to 2010 the right format is spx_ftse_00_10$Date <- as.Date(spx_ftse_00_10$Date, format = "%m/%d/%Y") the difference is the year Letter must be Y not y capital not small try this and tell me good luck M.Abd.Elhafez
