countCalls: Count the number of calls to one or more functions

In duncantl/CallCounter: Run-time code measurement and tools for helping debugging

Count the number of calls to one or more functions

Description

These functions allow one to count the number of calls to one or more functions.

Usage

countCalls(obj, counter = genCounter(), env = globalenv(), print = FALSE)
countMCalls(..., counter = genMultiCounter(funNames), env = globalenv(), print = FALSE,
            funs = substitute(list(...))[-1],
            funNames = sapply(funs, as.character))

Arguments

obj,...	the functions either as quoted namesto be
counter	the counter object to use, typically created via genCounter
env	the environment in which to evaluate the call to trace
print	passed on to trace
funs	an alternative way to specify the functions whose calls are to be counted. This allows the functions to be specified collectively in a list or character vector rather than individually via the ... mechanism.
funNames	the names of the functions, typically computed from the call itself. These are used to make updating the counts more efficient by not having to check if there is already a named element for the function in the integer vector.

Value

These function return the counter. This is a list with 3 functions

value	function to query the current count(s)
reset	function to reset the count(s) to 0, or to create a new empty integer vector if its parameter full is TRUE when calling it.
inc	the function called to increment the counter

replicate(10, dnorm(0))
replicate(7, rnorm(1))
dnorm(1)
ctr$value()
