peakRAM: Monitor the Total and Peak RAM Used by an Expression or Function
When working with big data sets, RAM conservation is critically
important. However, it is not always enough to just monitor the
size of the objects created. So-called "copy-on-modify" behavior,
characteristic of R, means that some expressions or functions may
require an unexpectedly large amount of RAM overhead. For example,
replacing a single value in a matrix duplicates that matrix in the
back-end, making this task require twice as much RAM as that used
by the matrix itself. This package makes it easy to monitor the total
and peak RAM used so that developers can quickly identify and
eliminate RAM hungry code.
