...ther job, your job will not be able to access the file and your job will crash because of that. To avoid this, you want your job to try to access the file repeatedly with some time interval, say every 10 seconds or something like that. Which is the best way to do this in R?

In those cases, things restored smoothly when the system is restarted. However, this time, this trick does not work.

Hello. By way of background, I am running out of memory when attempting to normalize the data from 160 affymetrix microarrays using justRMA (from the affy package).

Happy new year to all; A few days ago, I posted similar problem. At that time, I found out that our R program had been 32-bit compiled, not 64-bit compiled. So the R program has been re-installed in 64-bit and run the same job, reading in 150 Affymetrix U133A v2 CEL files and perform dChip processing. However, the memory problem happened again. Since the amount of physical memory is 64GB, I think
