ggplot2: facet_grid with different vertical lines on each facet
...ing facet_grid in ggplot2. However,
I want to then add a vertical line to each histogram, or facet, each of
which vertical lines are at different x-values.
The following example adds all vertical lines to each facet:
ggplot(data,aes(values)) + geom_histogram() + facet_grid(.~variable) +
geom_vline(xintercept=c(5,10,15))
How can I add a vertical line at different x positions on each facet?
Thanks very much,
Scott Chamberlain

líneas sobre un mapa
Buenos días ¿sabéis si hay alguna forma de añadir una recta vertical sobre
un mapa hecho previamente con ggplot? Lo que hago ahora es cargar
nuevamente el mapa con la línea añadida (una serie de líneas añadidas
secuencialmente en un loop) pero me gustaría que añadiese las líneas sin
cargar nuevamente el mapa.
Gracias,
Manuel

behaviour of read.xls (gdata package) when worksheet usesuser-defined cells formats

hi R-list,
And sorry for my frenglish !
I am running R < Good Sport > release ( i386-w64-mingw32/i386 (32-bit) ) ) under Windows 7 Professional, Service Pack 1.
My perl executable is ActivePerl build 817 [257965] (i.e. version 5.8.8.817). Usually it is working fine.
