On R 2.15.2 and ArcGIS 9.3.1, it works for me in ArcCatalog but you have to follow the particulars here:
http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=Accessing_delimited_text_file_data For example: write.table(test, '***.tab', sep = '\t', row.names = F) The extension .tab and sep = '\t' are required for text files. Didn't test row.names=T but I wouldn't count on that working either.

I think you need to provide a simple example for us to try, either by putting a small example of one of your files online for us to download, or (better) by giving us self-contained code to duplicate the problem. You might also get better help (especially about ArcGIS) on the R-sig-Geo mailing list: <https://stat.ethz.ch/mailman/listinfo/r-sig-geo>.
