The Title field should be in title case, current version then in title case: 'Ports the workflow of "Resampling Stats" add-in to R' 'Ports the Workflow of "Resampling Stats" Add-in to R'

I think adding Enconding:UTF-8 in DESCRIPTION solves the problem with non-ASCII characters. But since we have not detected this problem while checking in our machines and we also had enconding issues with vignettes please check.

From Writing R Extensions:

If the DESCRIPTION file is not entirely in ASCII it should contain an ‘Encoding’ field specifying an encoding. This is used as the encoding of the DESCRIPTION file itself and of the R and NAMESPACE files, and as the default encoding of .Rd files. The examples are assumed to be in this encoding when running R CMD check, and it is used for the encoding of the CITATION file. Only encoding names latin1, latin2 and UTF-8 are known to be portable. (Do not specify an encoding unless one is actually needed: doing so makes the package less portable. If a package has a specified encoding, you should run R CMD build etc in a locale using that encoding.)

So I guess the package will be accepted now.
