Problem of calculating the age

[boyaow]

I wrote the code to calculate the age of a person, but R shows me NA, what is the problem? I created the list and the list showed nothing wrong.

It looks fine. Did you run the chunk twice and convert your DateOfBirth twice?

> dob <- "9 February 1951"
> dob.as.date <- as.Date( dob, format="%d %B %Y" )
> dob.as.date
[1] "1951-02-09"
> Sys.Date()
[1] "2019-04-20"
> time.diff <- Sys.Date() - dob.as.date  # in days
> time.diff
Time difference of 24907 days
> as.numeric( time.diff ) / 365  # in years
[1] 68.23836

Just i n case, use:

Sys.setlocale("LC_TIME", "English")

Before making the date computation. Your computer may have a setting different than English.

Please, let us know it is working well.

I put this chunk of code before Sys.Date(), but it shows something else.

It's giving you an error when you are trying to set the locale time. Can you type sessionInfo() and share the results?

It's better if you share your code directly as text instead of a screen shot because it's easier for us to try the code to see where it might be broken.

I tried this code and it shows something below, actually I think that kind of problem does not show up after I changed my system language of the computer to English.

I can now run these code without the code
Sys.setlocale("LC_TIME", "English")
