R Read abbreviated month form a date that is not in English

Question

I have a text file that includes dates, and want to convert it to a datatable.

Converting the dates such as 03-FEB-2011 can be done with

data$fecha &         


        

Answer 1

As my previous comment, here is a complete and tested answer. As I've said you have to set your locale to the one right for your data (in this case spanish).

The code that allows you to do that is the following:

Sys.setlocale(locale="es_ES.UTF-8")

you can see the complete list of available locales with system("locale -a", intern = TRUE) (not sure if it works well on Windows systems).

Here is an example:

x <- c("03-Ago-2011", "21-Ene-2012")
as.Date(x, format = "%d-%b-%Y")
[1] "2011-08-03" "2012-01-21"
