gc
Garbage Collection

### Description

Collect unused memory and show memory usage.

### Usage

    gc(verbose = getOption("verbose"), reset = FALSE)
    gcinfo(verbose)

### Arguments

verbose | a logical value or object that can be coerced to logical value. If TRUE, gc will print a summary of memory usage.
reset | a logical value, this argument is provided for compatibility with open source R, and is ignored.

### Details

The object system allocates memory when requested, but frees it when the garbage collector is run to increase available memory by releasing objects which are not in use. Typically garbage collection is run when there is not enough memory to perform the next requested allocation, but it can also be run on demand. gc will perform garbage collection on demand. gcinfo is provided for compatibility with open source R and the function has no effect and always returns FALSE.
Value

gc | returns NULL
gcinfo | returns FALSE
