R中的每小时时间序列，转换e

Question

this should look like a dumb question but: I am trying to plot a time series of tweets by hourly basis. My time cell looks something like:

Thu Dec 05 13:27:46 +0000 2013

I can't figure out the way of converting it in a numerical value so to plot the convient frequency value of the tweets, by hour.

I used: as.POSIXct and as.date but always returning NA

What's wrong in something like:

test <- as.Date('Thu Dec 05 13:27:16 +0000 2013', "%a %b %d %H:%M:%S %z %Y")

?

Thanks to everyone :)

Answer 1

strptime('Thu Dec 05 13:27:16 +0000 2013', "%a %b %d %H:%M:%S %z %Y")

Answer 2

perhapse a little late, but I had exactly the same problem. Try:

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

and then re-run your code.
