Date conversion in R not registering string correctly -


can please tell me why doesn't work:

as.date("01/08/15", format = "%m/%d/%y") [1] "0015-01-08"

thanks!

you need use lower-case %y. upper-case %y requires 4-digit year. (in opinion, entire command should have failed error message, unfortunately didn't.) see strptime(), documents format codes.

as.date("01/08/15", format = "%m/%d/%y") ## [1] "2015-01-08"

go - Idiomatic way to handle template errors in golang -

say have html/template following: <html> <body> <p>{{somefunc .somedata}}</p> </body> and somefunc returns error. there idiomatic way deal this? if write directly responsewriter , status code 200 has been written before encounter error. var tmpl *template.template func handler(w http.responsewriter, r *http.request) { err := tmpl.execute(w, data) // "<html><body><p>" has been written... // err? } preferably return status code 400 or such, can't see way if use template.execute directly on responsewriter . there i'm missing? since template engine generates output on-the-fly, parts of template preceding somefunc call sent output. , if output not buffered, (along http 200 status) may sent. you can't that. what can perform check before call template.execute() . in trivial case should enough call somefunc() , check return value. if choose path , return value of somefunc() c...
