In basille/basr: Basic, but hopefully useful, functions

Description Usage Arguments Value Original URL Author(s) Examples

Show memory usage of saved objects.

memUse(pos = 1, pattern)

## S3 method for class 'memUse'
print(x, sort = c("size", "alphabetical"),
  decreasing = ifelse(sort == "size", TRUE, FALSE), n = 10, bytes = FALSE,
  ...)

`pos`	Which environment to use to list the saved objects (as a position in the search list). See `ls`.
`pattern`	An optional regular expression. See `ls`.
`x`	An object of class `memUse`.
`sort`	Whether to sort the object list by `size` or `alphabetical` order.
`decreasing`	Logical. Should the sort order be increasing or decreasing?
`n`	A single integer, giving the number of objects to display.
`bytes`	Logical. Whether to display the raw size in bytes.

A data frame of classe memUse providing object names, class and memory usage; or 0 if no object is present in the specified environment.

foo <- function(x) print(x)
##'
## Check memory usage (and raw numbers in bytes)
memUse()
memUse()$bytes
