R: plot dates in specific locale

问题

I build a vector d of POSIXlt dates. I make a plot(d, x) using this vector as axis x. but on the plot dates are printed using my computer's locale. I need them to use different locale. how can i choose the format/locale to be used on plots?

You should be able to use on Unix based system:

Sys.setlocale("LC_TIME", "en_US"); 

This works for me:

Sys.setlocale("LC_TIME","ru_RU")

df = data.frame(date=c("2012-02-01", "2012-02-01", "2012-02-02")) 
df$day <- weekdays(as.Date(df$date))
df$value <- c(1,10,5)

plot(df$value, xaxt="n") 
axis(side=1, labels=df$day, at=c(1,2,3))

Sys.setlocale("LC_TIME","en_US")

df = data.frame(date=c("2012-02-01", "2012-02-01", "2012-02-02")) 
df$day <- weekdays(as.Date(df$date))
df$value <- c(1,10,5)

plot(df$value, xaxt="n") 
axis(side=1, labels=df$day, at=c(1,2,3))
