I'm about to commit a fix to this  "age old" typo,
using "R-squared" in both cases as Jeff suggests,
unless some R-corer tells me I should not.

Yes, indeed, two *.Rout.save files need to be replaced too,
but I don't think that this --- and the fact that the output in many
books will eventually be "wrong" by a difference of 
      ' "r" - "R" '
would be good enough reason to keep this inconsistency.

    JR> Hi.

    JR> I almost feel bad reporting this, but here goes.

    JR> The summary() for lm() (and possibly others?) uses a capitalized `S' in Multiple
    JR> R-Squared but a lowercase `s' in Adjusted R-squared. For instance,

    JR> Residual standard error: 0.5608 on 202 degrees of freedom
    JR> Multiple R-Squared: 0.2308,     Adjusted R-squared: 0.2232 
    JR> F-statistic:  30.3 on 2 and 202 DF,  p-value: 3.103e-12 

    JR> Perhaps they both ought to be lowercase? Again, truly trivial but perhaps it
    JR> adds to the overall polish...

    JR> -- Jeff
