Dear all,    Have been trying to use random forest for classification and i keep getting the error cannot allocate vector size of 1.8 Gb.  I am working on R 64 bits under windows 64 bits.   I had a 3gb ram and then upgraded it to 8 to try to solve the problem.  But still not working and have the same error.  Any help? Regards,salwa
