Hi Fabio,
If you have more than a few dates on the X axis you may get
overlapping tick labels. As an example, take a plot of the winning
parties of by-elections held in Australia in the 21st century by the
dates of the elections:
be_dates<-as.Date(c("5/12/2015","19/09/2015","8/2/2014",
"5/12/2009","6/9/2008","6/9/2008","28/6/2008","19/3/2005","19/10/2002",
"14/7/2001","17/3/2001","12/8/2000"),"%d/%m/%Y")
be_parties<-factor(c("Lib","Lib","Lab","Lib","Ind","Lib","Nat",
"Lab","Grn","Lib","Lab","Lab"))
par(mar=c(6,4,4,2))
plot(be_dates,be_parties,xaxt="n",yaxt="n",
xlab="",ylab="Winning party",pch=as.numeric(be_parties))
require(plotrix)
staxlab(1,at=be_dates,labels=format(be_dates,"%d/%m/%Y"),nlines=4)
axis(2,at=1:5,labels=levels(be_parties))
mtext("By-election dates",side=1,line=4)
As you can see, most dates would overlap other dates using the standard axis.
