Dear R Gang:
	I have a Macintosh G4 powerbook, running OS 9.2.  Last week I 
ran a statistical analysis program that I wrote in R for two days 
continuously.  The program does repeated intensive computations on a 
large data set.
	The program completed its task successfully, but during the 
process I noted that the computer seemed to be running unusually hot. 
Shortly after the program stopped, something unrepairable happened to 
the computer.  I don't know the cause of the problem yet, and won't 
find out until Monday or Tuesday, but it seems to involve the hard 
drive - Norton Disk Doctor cannot fix it, nor can I restore the 
original software to the hard drive.
	The computer breakdown may of course be unrelated to my use 
of R, but I am concerned that running the computer so intensively may 
have caused the problem.  Has anyboody run into a similar problem 
using R on a G4 machine?  I have also been running R on a G3 I-Book, 
using the same operating system, though not the same program, and I 
have had no problems.
