You need to put the format in quotes.  R sees %d-% as a "SPECIAL" 
operator, and it is an error for one of those to appear in that position.

So use

as.Date(all.2015$Day, "%d-%m-%y")

(and be careful of the quotes:  these are regular ASCII quotes, not directional
quotes which some editors will insert).
