r - source() taking long time and often crashed -


i used dump() command dump dataframes in r. particular dump files 200 mb, , 1 about1.5 gb. later tried retrieve them using source() , taking lot of time , says windows stopped working after 3-4 hours. using 64 bit r 3.0.0 ( tried in r 2.15.3 too) in windows 7 memory of 48 gb. 1 of file, threw memory error, (i don't have log now) loaded 4-5 datasets out of 15 datasets.

is there way can load particular dataset if know name? or there other way?

i have learned lesson , save command create data , original data. or 1 data in 1 dump file (or r image file)

thank you

use save() , load() rather dump() , source().

save() writes out binary representation of data .rdata file, can loaded in using load().

dump() converts text representation, source() has reconvert binary. both ends of process very inefficient.
