A Comprehensive Guide to Handling Dates with as.Date in R Programming

    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.

    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?
