For R, there is no difference between "-" and "." in package version
numbers. Here is what the R Extension manual says:

"The version is a sequence of at least two (and usually three)
non-negative integers separated by single ‘.’ or ‘-’ characters. The
canonical form is as shown in the example [0.5-1 - Martyn], and a
version such as ‘0.01’ or ‘0.01.0’ will be handled as if it were
‘0.1-0’."

So you should just replace dashes with dots.
