Dear all
I try to format labels on axis as standard ones does not look well, but I
am not able to make axis.POSIXct to work. here is an example
x<-seq(as.Date("2008-1-1"), as.Date("2009-9-6"),
by="2 months")
y<-rnorm(11)
plot(x,y) #not very sophisticated axis
plot(x,y, axes=F)
axis(2)
axis.POSIXct(1, at=x, format="%m/%Y") # no axis
The same is on R2.10.0, 2.10.dev and 2.11.dev

Is it a bug or am I missing something?

Your example works if I do: axis.Date(1, at=x, format="%m/%Y") The examples in ?axis.Date show that this does work using axis.POSIXct if one does have a POSIXct object.

Thanks. I did not read help page carefully and overlooked axis.Date Regards Petr Gavin Simpson <gavin.simpson at ucl.ac.uk> napsal dne 05.11.2009 10:43:22:> On Thu, 2009-11-05 at 10:28 +0100, Petr PIKAL wrote: > > Dear all > > > > I try to format labels on axis as standard ones does not look well,but I> > am not able to make axis.POSIXct to work. here is an example > > But you are plotting an axis using an object of class "Date", so why use > axis.POSIXct? > > Your example works if I do: > > axis.Date(1, at=x, format="%m/%Y") > > The examples in ?axis.Date show that this does work using axis.POSIXct > if one does have a POSIXct object. > > HTH > > G > > > > > x<-seq(as.Date("2008-1-1"), as.Date("2009-9-6"), by="2 months") > > y<-rnorm(11) > > plot(x,y) #not very sophisticated axis > > > > plot(x,y, axes=F) > > axis(2) > > axis.POSIXct(1, at=x, format="%m/%Y") # no axis > > > > The same is on R2.10.0, 2.10.dev and 2.11.dev > > > > R session > > > > > version > > _ > > platform i386-pc-mingw32 > > arch i386 > > os mingw32 > > system i386, mingw32 > > status > > major 2 > > minor 10.0 > > year 2009 > > month 10 > > day 26 > > svn rev 50208 > > language R > > version.string R version 2.10.0 (2009-10-26) > > > > Czech Locale > > > > Is it a bug or am I missing something? > > > > regards > > Petr > > > > ______________________________________________ > > R-help at r-project.org mailing list > > https://stat.ethz.ch/mailman/listinfo/r-help > > PLEASE do read the posting guidehttp://www.R-project.org/posting-guide.html> > and provide commented, minimal, self-contained, reproducible code. > -- > %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% > Dr. Gavin Simpson [t] +44 (0)20 7679 0522 > ECRC, UCL Geography, [f] +44 (0)20 7679 0565 > Pearson Building, [e] gavin.simpsonATNOSPAMucl.ac.uk > Gower Street, London [w] http://www.ucl.ac.uk/~ucfagls/ > UK.
