[R] Date format on x-axis

[inaki at goisolutions.net]

Dear R users,

Plotting question from a R beginner...

When I try to plot a response through time, for example:
>Date<-c("2006-08-17", "2006-08-18", "2006-08-19", "2006-08-20")
>response<-c(4,4,8,12)
>as.Date(Date)
>plot(Date,response)

The dates on the graphic appear in spanish. This I guess is the default
way of plotting because my windows is in spanish, but I need a "aug 17"
instead of "ago 17" (agosto is the spanish for august)...
I've tried,
>format(Date, "%m %d")
And although it does change the way Date is listed, well it's still
plotted in spanish...
I've also searched through par() settings, but xaxp,xaxs, xaxt, xpd and
xlog do not solve my problem...

Could anyone help me solve this format question?

Thanks a million in advance,
