[R] Problem with expand.grid

[Keith Jewell]

Just confirming it isn't the bug fixed in 2.11.0dev, and giving an even 
simpler example:

R version 2.11.0 Under development (unstable) (2009-12-20 r50794)

> expand.grid(data.frame(y=1:10, t=1:10))
Error in `[[<-.data.frame`(`*tmp*`, i, value = c(1L, 2L, 3L, 4L, 5L, 6L,  :
  replacement has 100 rows, data has 10
