A Comprehensive Guide to Handling Dates with as.Date in R Programming
code
date = Sys.Date()
date
class(date)
typeof(date)
mode(date)
date_string = "2023-05-30"
class(date_string)
typeof(date_string)
mode(date_string)
as.Date(), as_date(), as_datetime(),strptime()
"2023-05-30"
"2023-30-05"
"05-30-2023"
'05/30/2023'
date_1 = as.Date("2023-05-30") # yyyy-mm-dd
date_1
class(date_1)
date_2 = as.Date("05-30-2023", format="%m-%d-%Y") # mm-dd-yyyy
class(date_2)
date_3 = as.Date("05/30/2023", format="%m/%d/%Y") # mm/dd/yyyy
class(date_3)
date_4 = as.Date("05 30 2023", format="%m %d %Y") # mm dd yyyy
class(date_4)
date_5 = as.Date("05 Tue 30 2023", format="%m %a %d %Y") # mm wday dd yyyy
class(date_5)

What a GREAT teacher professor Choure. We need more professors like you to spread the gospel about using R for data analysis/science, this wonderful tool has been undermined for too long.

Thanks for good words. This appreciation really motivates to work more.
great video, did we can change 2 different type of date was save in one list to date type . c("2010-10-12", "11-10-2010") ?

Yes. We can. Just use tryFormats=c("format1","format1"...) In arguments of as.Date()
Well explained. What if I want to convert a whole column and find the difftime?

# any format # Install and load the anytime package install.packages("anytime") library(anytime) # Your data frame with a column of date strings (assume it's named 'date_column') your_data_frame
The date also contained time data. How do I convert and find the difftime?
