A call of gc causes a garbage collection to take place.
gcinfo sets a flag so that automatic collection is
either silent (verbose = FALSE) or prints memory usage
statistics (verbose = TRUE).
gc();A call of gc causes a garbage collection to take place. This will also take place automatically without user intervention, and the primary purpose of calling gc is for the report on memory usage. For an accurate report full = TRUE should be used. It can be useful To Call gc after a large Object has been removed, As this may prompt R To Return memory To the operating system. R allocates space For vectors In multiples Of 8 bytes: hence the report Of "Vcells", a relic Of an earlier allocator (that used a vector heap). When gcinfo(TRUE) Is in force, messages are sent to the message connection at each garbage collection of the form:
Garbage collection 12 = 10+0+2 (level 0) ...
6.4 Mbytes of cons cells used (58%)
2.0 Mbytes of vectors used (32%)
