update PCcontrib example to access the ggplot object in the list output

[benmarwick]

Because the current example gives an error in Momocs_1.2.9:

gg <- PCcontrib(bot.p, nax=1:8, sd.r=c(-5, -3, -2, -1, -0.5, 0, 0.5, 1, 2, 3, 5)) gg + geom_polygon(fill="slategrey", col="black") + ggtitle("A nice title") Error in gg + geom_polygon(fill = "slategrey", col = "black") + ggtitle("A nice title") : non-numeric argument to binary operator

Seems that you didn't merge the changes, only closed the PR? Just curious if that was your intention or an accident. Thanks
