R help - Jul 2015 - multiple graphs with a single legend and trellis graph

Dear Jim,

first of all, thank you very much :) 
when I run the code:

myDF <- rbind(mse.alpha1, mse.alpha2)  # assumes both data frames have the
same variables in the same order


myDF$ID <- factor(rep(c("alpha1", "alpha2"), times
c(nrow(mse.alpha1), nrow(mse.alpha2))) )


library(reshape2)
myDF.melt <- melt(myDF, id = c("ID", "nsample",
"lambda"), measure c("mse.naive", "mse.RegCal",
"mse.PL"))  #Melt the three columns to be plotted, something like

library(ggplot2)
ggplot(myDF.melt, aes(x = lambda, y = value, color = variable)) +
   geom_point() + geom_line() +
   facet_grid(ID ~ nsample) +
   labs(x = expression(paste(lambda)), y = "MSE", color = "Type?)



 I get the attached graph. I also attach my data, so you can see :)

I?m I able to resize the graphs differently? I.e. for alpha1: ylim=ylim=c(0,.6)
and for alpha2: ylim=c(0,.17)?
I reshaped, a new variable in sample was created, NA, Was it me that made
something wrong?

I?m very naive and new in R :(

Thanks again ;)







Atenciosamente,
Rosa Oliveira

Hi Rosa,
Neither the graph nor the data arrived.  R-help can be very fussy about what
attached files it will accept. Usually pdf, txt and png, I think, will come
through.

In any case it is much better to supply data using the dput() function See ?dput
or have a look at
http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example
and http://adv-r.had.co.nz/Reproducibility.html for how to do this.

It is best to use dput() rather than supplying a data file because dput()
ensures that we get an exact copy of the data as it exists on your computer. 
There is no real guarantee that I will read in a data file the same way as you
have.
