Hi. My bioconductor.org package, EBImage, should do that -- it allows you to specify the structuring element, which can be a circle of any given radius if you want. The package includes erosion, dilation, opening and closing. It is also a general package for image analysis and processing built around ImageMagick library with many functions added. The only minus, still no Windows support -- Linux, Unix or Mac.
