If you have Perl running, you need a current version of gdata

require(gdata)
installXLSXsupport()   #now the example from help(read.xls)
    # load the third worksheet, skipping the first two non-data lines...
    if( 'XLSX' %in% xlsFormats() )  # if XLSX is supported..
      data <- read.xls(exampleFile2007, sheet="Sheet with initial text", skip=2)
 data
#-----------------------
   X       X.1 D E.  F  G Factor
1 NA  FirstRow 1 NA NA NA   Red 
2 NA SecondRow 2  1 NA NA Green 
3 NA  ThirdRow 3  2  1 NA   Red 
4 NA FourthRow 4  3  2  1 Black 
#------------------------
write.csv(data)

This was done on a Mac and up until this question I had always stumbled at the installXLSXsupport() stage since I always got an error. This time I started up Perl from a Terminal command line, and got success after first setting up my personal configuration, defining CPAN mirrors on my continent, and I left perl running.
