hi,
i did a 2^4 factorial experiment, and i got the following result:
Effect t p (computer)
p -484.52494328125 -5.64590926071629 <0.0001

pdts -50.64764015625 -0.5901697829117 0.5633
and i want to plot those whose are significant in R for an interaction plot
to see their effect?
but i don't know how to do it in R, all i know is using 'interaction.plot()'
can anyone help me out what i need to put in for the plot?
many thanks.
