Documentation for SLiM function usage, which is a method of the SLiM class Community. Note that the R function is a stub, it does not do anything in R (except bring up this documentation). It will only do anything useful when used inside a slim_block function further nested in a slim_script function call, where it will be translated into valid SLiM code as part of a full SLiM script.

usage(void)

Arguments

void

An object of type . See details for description.

Value

An object of type float. Return will be of length 1 (a singleton)

Details

Documentation for this function can be found in the official SLiM manual: page 669.

Return the current memory usage of the simulation. The specifics of what is totalled up should not be relied upon as it may change from version to version of SLiM. This method is primarily useful for understanding where the memory usage of a simulation predominantly resides, for debugging or optimization. Note that it does not capture all memory usage by the process; rather, it summarizes the memory usage by SLiM and Eidos in directly allocated objects and buffers. To see details of this internal memory usage, use the Community method outputUsage(). To get the total memory usage of the running process (either current or peak), use the Eidos function usage().
