...r Hadley Wickham followed up with "I think all you want
here is rbind.fill:"
resultDF6 <- rbind.fill(mylist)
all.equal(resultDF, resultDF6)
## Gabor Grothendieck noted that if the elements in mylist were
matrices, this would all work faster.
mylist2 <- lapply(mylist, as.matrix)
matrixDoCall <- do.call("rbind", mylist2)
all.equal(as.data.frame(matrixDoCall), resultDF)
## Gabor also showed a better way than 'system.time' to find out how
## long this takes on average using the rbenchmark package. Awesome!
