Hi all,
I have the following data. I want to plot the data (y ~ conc)
with different symbols and colors corresponding to different levels of the
factor sample.
I could create a column with color and pch and then do the plot, but I am
sure there are much better ways.
Can anyone make suggestions?
Hanna
