Hi Steven,
 
If you have access to Beadstudio, probably the easiest way to get Illumina SNP data loaded in beadarraySNP is the following
- Do genotyping of your data in Beadstudio
- Create a final report (From the Analysis->Reports menu) that contains at least the fields 'SNP Name', 'Sample ID', 'GC Score', 'Allele1 - AB', 'Allele2 - AB', 'GT Score', 'X Raw',  'Y Raw', 'Chr' and 'Position'. Any other fields you select here will also be imported. Be sure to enable the checkbox to create a 'Sample MAP'
- Now you can use the sample_map.txt file as a samplesheet by using the Sample_Map2Samplesheet() function
- load the data: mydata<-read.SnpSetIllumina(Sample_Map2Samplesheet("Sample_Map.txt"),reportfile="reportfile.txt")
