Paul:
This simply is not supported. Look at parse.format() in the chron pkg.
What it does is
* if format has 5 chars, parse as "a/b/c"
* if format has 3 chars, parse as "abc"
* else parse as "a b c" (and do not abbreviate month names if
"month" is
given.
In you example, we get
R> unlist(parse.format("yy/m/d"))
abb sep periods mon.abb
"FALSE" " " "y" "TRUE"
and hence we only get the years.
Hope this helps.
Best,
