Hi,
I had problems to display my results in a nice way (according to me).
Thanks to posts of people of this forum, I solved my problems (ticks with a
scientific notation and how to write nicely "V/m2" in the label of the
x-axis) but ... I don't understand the script.
Can somebody explain me how the short script below writes the scientific
notation ?
I guess it is the result of
ans$bottom$labels$labels <- parse(text = ans$bottom$labels$labels)
but it is really not clear to me.
Thanks in advance for your explainations
Ptit Bleu.

y<-c(1,2,3,4,5,2,4,6,8,10)
z<-c(1,1,1,1,1,2,2,2,2,2)
xyplot(y ~ x | z,
scales = list(x = list(log = T)),
xscale.components = function(...) {
ans <- xscale.components.default(...)
ans$bottom$labels$labels <- parse(text
= ans$bottom$labels$labels)
ans
}
, xlab=(expression(paste("X (V/",m^2,")"))) , ylab="Y (arb. unit)")
