Oh, thanks, that was hint enough :-) I see it now. I turns that R does not understand
e-10 ...which stands for 1e-10 and is produced by some of the bioinformatic applications that I use (notably BLAST). However, R instead of being verbose on that just assumes that the whole column is a string. Is there a way to enforce a specific conversion in R (for example, to be able to see where the errors are?).
