Ahhhh, again, the orgiginal code really helps to help:
A csv file does only contain the data values, all other structure of the 
object is lost. You can either directly ask

plot(mult.comp)

after your second line, or in order to plot later on, use save() to save 
the objects as an Rdata file and use load() to load it later on (e.g. 
for plotting purposes.

Best,
