Hi.
I'm using R1.3.1 on a x86 machine running Win 2000.
My problem:
- I want to convert a string to a date format using strptime. As I'm from
Portugal my locale information is the following:
> Sys.getlocale()
[1]
"LC_COLLATE=Portuguese_Portugal.1252;LC_CTYPE=Portuguese_Portugal.1252;LC_MO
NETARY=C;LC_NUMERIC=C;LC_TIME=Portuguese_Portugal.1252"
If I do the following everything works fine :
> k <- "25-Set-01"
> strptime(k,"%d-%b-%y")
[1] "2001-09-25"
because the month September in Portuguese is named "Setembro" and thus
is
abbreviated as "set" and not "sep" as in English.
However, I'm interested in reading English dates. I was hoping that the
following would solve my problem:
> Sys.setlocale("LC_TIME", locale="USA")
[1] "English_United States.1252"
However, I get the following error :
> k <- "25-Sep-01"
> strptime(k,"%d-%b-%y")
[1] "NA"
Thank you for any help with this.
