try to be more specific, ie. isolate the exact line of code that triggers the memory problem and then think about why this may happen (large data, too many covariates, etc.). Then scale down the problem on the dimension that you think creates the problem (eg. by subsetting the data) and run it again. do this iteratively until you figured out the exact source of the problem so we can think about solutions. you can also try to run the gc() command to reallocate memory before running this command.

I appreciate the help.

I've been working for about three hours just to solve these problems, but it seems as though there isn't much else I can do. I tried opening R with various startup commands from Terminal-- I've tried various values for the startup parameters with no success. I'm not really sure where to go from here. Does anybody have any suggestions? _______________________________________________ gov2001-l mailing list gov2001-l at lists.fas.harvard.edu http://lists.fas.harvard.edu/mailman/listinfo/gov2001-l Dr Jeremy Hodgen Senior Lecturer in Mathematics Education King's College London Department of Education and Professional Studies Franklin-Wilkins Building Waterloo Bridge Wing 150 Stamford Street London SE1 9NH Tel: 020 7848 3102 Fax: 020 7848 3182 E-mail: jeremy.hodgen at kcl.ac.uk _______________________________________________ gov2001-l mailing list gov2001-l at lists.fas.harvard.edu http://lists.fas.harvard.edu/mailman/listinfo/gov2001-l
