Dieter,
I'd approach this by first making a matrix, then converting to a data
frame with appropriate types. I'm sure there is a way to do it with
structure in one step. Operations on matrices are usually faster than on
dataframes.
len - 10
d - replicate(len, list(pH = 3, marker = TRUE,
The as.numeric(d.df$pH) should have been an
as.numeric(as.character(d.df$pH)).
Sorry for the confusion.

Well, I knew that matrixes are faster for numerics, but I also knew that the
