Hello, All:

Prof. Ripley suggested I remove RTools/perl from my path. I did that leaving Strawberry perl. Then everything seemed to work appropriately.


      Thanks to all.
      Spencer

      I tried "install.packages('gregmisc')", which Stephen said he had.
  Then " help(pac=gdata)" seemed to work normally.  However, when I then
tried "library(gdata)", I got an error message from the the operating
system, saying "perl.exe has stopped working".  I cancelled past that and
got a message "gdata: Unable to load perl libaries needed by read.xls() ...
Run the function 'installXLSXsupport()'".  I tried 'installXLSXsupport()'
and again perl stopped working.  I quit R and tried
"install.packages('gdata')" again, and it killed perl again.


      Before installing 'gregmisc', I had tried install.packages('gdata') by
itself.  That seemed to work.  Then I manually removed it and tried
'gregmisc', as Stephen had, and got problems I don't know how to solve.
