[R] how to get the value of aov summary into another variable

[Peter Alspach]

Waverley

In general, examine the structure of the object and go from there.
Thus:

str(summary(aov.ex))

will reveal that summary(aov.ex) is a list of 1.  Thus you probably want
to examine that single element in more detail:

str(summary(aov.ex)[[1]])  # the [[1]] to get the first element of the
list

This is a data.frame, and hence:

summary(aov.ex)[[1]][,4:5]

will give what you want.  You can, of course, assign this to another
object if you like.  Incidentally, anova(aov.ex)[,4:5] is somewhat more
direct.
