Hi,

I moved to lmer 1.0-4 and R 3.0.2. Now lmer() and glmer() functions are
working much slower than before, and I get the following warning message,
which I suspect is related to that.

Warning in rankMatrix(X) :
  rankMatrix(<large sparse Matrix>, method = 'tolNorm2') coerces to dense
matrix.
  Probably should rather use  method = 'qrLINPACK' !?

Do you have any advice on this? Where can I change the method of the
rankMatrix()?

Many thanks in advance,

Best,

Juan
