Dear all,
I am running
R : Copyright 2005, The R Foundation for Statistical Computing
Version 2.1.1 (2005-06-20), ISBN 3-900051-07-0
Under Mac os X, a french version!
There is no `french version', but you may be in a French locale.
I am preparing a package and I got the following issue
I am trying to read dates that are written in
english and have them recognized by R using
as.Date function.
I realized strangely that when I type
month.abb
[1] "Jan" "Feb" "Mar" "Apr" "May" "Jun" "Jul" "Aug" "Sep" "Oct"
[11] "Nov" "Dec"
I get the abbreviated english version of every month
x <- c("1-jan-1960", "2-feb-1960",
"31-mar-1960", "30-apr-1960","2-may-1960",
"31-jun-1960", "30-jul-1960","2-aug-1960",
"31-sep-1960", "30-oct-1960", "30-nov-1960",
"30-dec-1960");
strptime(x, "%d-%b-%Y")
[1] "1960-01-01" NA "1960-03-31" NA
[5] NA NA "1960-07-30" NA
[9] "1960-10-01" "1960-10-30" "1960-11-30" NA
It is only once I have found through trial an
error the french abbreviation, that I got a match
for every month.
x <- c("1-jan-1960", "2-fév-1960",
"31-mar-1960", "30-avr-1960","2-mai-1960",
"31-jui-1960", "30-jul-1960","2-aoû-1960",
"31-sep-1960", "30-oct-1960", "30-nov-1960",
"30-déc-1960");
strptime(x, "%d-%b-%Y")
[1] "1960-01-01" "1960-02-02" "1960-03-31" "1960-04-30"
[5] "1960-05-02" "1960-07-01" "1960-07-30" "1960-08-02"
[9] "1960-10-01" "1960-10-30" "1960-11-30" "1960-12-30"
I got simply two questions:
First, why since R was install on a french system
the month.abb command didn't give me the french
abbreviations.
Did you read the help page, as we do ask?
* 'month.abb': the three-letter abbreviations for the English
month names;
* 'month.name': the English names for the months of the year;
Secondly, since I am producing a package, I would
like to know how can I tell R to momentairly use
the english abbreviations instead of the french
ones...
To use them for what? If you mean in strptime, set the locale you want.
There is an example on the help page!
Please do remember to read the help pages before posting.
