Hi. I've already posted this question 2 months ago but as I've got no
answer I've decided to try again :-)
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 in advance for any help with this,
Luis Torgo
