curfnfinder(skipframes = 0, skipnames = "(FUN)|(.+apply)|(replicate)",
            retIfNone = "Not in function", retStack = FALSE,
            extraPrefPerLevel = "\t")

`skipframes`	Number of frames to skip; useful when called from an anonymous function.
`skipnames`	A regular expression specifying which substrings to delete.
`retIfNone`	What to return when called from outside a function.
`retStack`	Whether to return the entire stack or just one function.
`extraPrefPerLevel`	Extra prefixes to return for each level of the function.
