The result is returned as " preparing geneSet collections... GSEA analysis... leading edge analysis... done... Warning messages: 1: In preparePathwaysAndStats(pathways, stats, minSize, maxSize, gseaParam, : There are ties in the preranked stats (1% of the list). The order of those tied genes will be arbitrary, which may produce unexpected results. 2: In serialize(data, node$con) : 'package:stats' may not be available when loading 3: In serialize(data, node$con) : 'package:stats' may not be available when loading 4: In serialize(data, node$con) : 'package:stats' may not be available when loading 5: In serialize(data, node$con) : 'package:stats' may not be available when loading 6: In serialize(data, node$con) : 'package:stats' may not be available when loading"

why is this happening?
