    extlib(packages)

    user_lib()

    packrat_lib()

### Arguments

`packages` | A set of package names (as a character vector) to load for the duration of evaluation of `expr`.
`expr` | An R expression.
`envir` | An environment in which the expression is evaluated.

### Examples

    ## Not run:
    with_extlib("lattice", xyplot(1 ~ 1))
