Useful, yes. Easy for someone unable to learn any
code, probably not. However, if what you want to do
can be done using the R-commmander (Rcmdr) package (a
graphical user interface which does offer cluster
analysis and anova, among other things, from a drop
down menu), then you may not need to write any code.
And Rcmdr will write the underlying code for you, so
you can save it and reproduce your work the next day
without pointing and clicking another 30 times. Still,
even using Rcmdr, when I first started I had to do a
lot of reading and searching to figure out seemingly
simple tasks. It's worth the effort if you think you
will continue to do statistical analysis in the
future, and thus earn a return on you intitial
