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.
