[R] Improve lattice XYPLOT graphic

[Marcelo Laia]

Hi,

How I could improve this graphic?

http://www.divshare.com/download/10754700-f81

I would like to write groups labels in each panel and override the
labels from object.

I am try this code:

xyplot(percentagem.mortos~tempo|trat, data=bio.ens, type="a",
      auto.key=list(points=FALSE, lines=TRUE, columns=3),
      ylim=c(0,100),scales = list(x = list(at = c(48, 72, 96), labels
      = c("48", "72", "96")), cex=2.0),
      ylab=list(expression("Percentagem de mortos"),cex=2.5),
      xlab=list(expression("Horas após aplicação"), cex=2.5), between
      = list(x = c(0.25, 0.25), y = 0.25), par.settings =
      simpleTheme(col="blue", pch=20, cex=2.3, lwd=6), par.strip.text
      = list(lines = 1, cex = 1.5),
#strip = strip.custom(strip.names=c(TRUE, FALSE),
#strip.levels=c(FALSE,FALSE),
#  var.name=expression(c(113 - 3%*%10^8,H_2O))
#factor.levels=expression(c(113 - 3%*%10^8,H_2O))
)


I already tried many options, but with out success. Google have showed
me many suggestions, like this one:

http://tolstoy.newcastle.edu.au/R/e2/help/06/09/1409.html

I had used this suggestion and the next code to pass the groups labels
to xyplot:

levs <- c(expression(133 - 3%*%10^8), expression(H_2O),
         expression(H_2O+Tween), expression(113 - 1%*%10^8),
         expression(113 - 3%*%10^8), expression(133 - 1%*%10^8))

without success.

I tried to change the labels on data file and/or bio.ens object, but no success.

Do you have any suggestion for me?

Different colors with legend?

What you suggest me?

113 and 133 are different isolates. 1%*%10^8 and 3%*%10^8 are
different treatments. H_2O and H_2O+Tween are my controls.

Any suggestion is very welcome!

Thank you very much
