anydate sometimes yields NAs

[drolejoel]

Hi Dirk, for some input values I am getting NAs. Is this a bug?

Might be related to bug#33 which I reported before but was fixed SOv report

library(anytime)  # V 0.3.0
a <- c("3/22/2013 0:00", "3/21/2012 0:00", "2/19/2014 0:00", "12/5/2013 0:00", "5/8/2013 0:00", "10/15/2010 0:00")
anydate(a)
# [1] "2013-03-22" "2012-03-21" "2014-02-19" NA           NA          
# [6] "2010-10-15"

Please see #67 which appears to be the same issue which I still cannot reproduce.

Also preferably use current versions. R 3.3.2 is old.

I take that back. User error. You cannot use single digit-months with the Boost parser. That is (as I recall) documented:

> library(anytime)
> dv <-a <- c("3/22/2013 0:00", "3/21/2012 0:00", "2/19/2014 0:00", "12/5/2013 0:00", 
+                   "5/8/2013 0:00", "10/15/2010 0:00")
> dv
[1] "3/22/2013 0:00"  "3/21/2012 0:00"  "2/19/2014 0:00"  "12/5/2013 0:00" 
[5] "5/8/2013 0:00"   "10/15/2010 0:00"
> anytime(dv)
[1] "2013-03-22 07:00:00 CET"  "2012-03-21 00:00:00 CET" 
[3] "2014-02-19 00:00:00 CET"  NA                        
[5] NA                         "2010-10-15 00:00:00 CEST"
> anytime(dv, useR = TRUE)
[1] "2013-03-22 CET"  "2012-03-21 CET"  "2014-02-19 CET"  "2013-12-05 CET"

But we now have a fallback as shown.

I tried setting the useR argument to TRUE but saw some weirdness. I'll have to update R and get back to you with my findings.

anydate(a, useR = TRUE)
[1] "3736219-12-27" "3649640-10-17" "3815239-04-08" "3797261-01-27"
[5] "3747338-01-29" "3525922-06-12"

anydate(a, asUTC = TRUE)
[1] "2013-03-22" "2012-03-21" "2014-02-19" NA NA
[6] "2010-10-15"

anydate(a, asUTC = TRUE, useR = TRUE)
[1] "3736219-12-27" "3649640-10-17" "3815239-04-08" "3797261-01-27"

Fix your inputs. You may have missed the part where I said:

You cannot use single digit-months with the Boost parser.

and there is nothing I can do about his. Sorry.

[drolejoel]

Then I mis-understood your instruction to use the useR argument. I was under the impression that by setting useR = TRUE it would not use the Boost parser and therefore it would instead go via code from R (and which would be able to handle single digit-months).

Thank you for your super-fast responses to my questions.

Good news - this now works in master (and hence the next release probably at the end of the month):

 R> a <- c("3/22/2013 0:00", "3/21/2012 0:00", "2/19/2014 0:00", "12/5/2013 0:00", 
+                "5/8/2013 0:00", "10/15/2010 0:00")
 R> library(anytime)
 R> anytime(a)
 [1] "2013-03-22 CDT" "2012-03-21 CDT" "2014-02-19 CST"
 [4] "2013-12-05 CST" "2013-05-08 CDT" "2010-10-15 CDT"
