learning R

Ah! That is interesting!

...

Otherwise, I am always amazed that people could use a metaphor like
here, a reference to the shape of a curve on a graph, without even
knowing what exactly are the X- and Y-axes. Shame on us!

Nothing to be ashamed of: We all know what is steep even if we cannot graph
it. 

I just wonder why the other supposed "misuse" was completely ignored in this
thread: there are many things in R that are "begging the question" but
nobody dares to ask.
