R devel - Feb 2017 - BUG: the quiet option in the install.packages function

Dear utils/R Package maintainers,

Since I'm still using version 3.3.2, please ignore this message if the bug
has already been fixed.

*BUG: *
The install.packages function still generate outputs even if
set quiet=TRUE.

*POSSIBLE REASON:*
The issue is seemly due to that the quiet parameter was not passed to the
download.file function.

#############################
install.packages(pkgs, lib, repos = getOption("repos"),
                 contriburl = contrib.url(repos, type),
                 method, available = NULL, destdir = NULL,
                 dependencies = NA, type = getOption("pkgType"),
                 configure.args = getOption("configure.args"),
                 configure.vars = getOption("configure.vars"),
                 clean = FALSE, Ncpus = getOption("Ncpus", 1L),
                 verbose = getOption("verbose"),
                 libs_only = FALSE, INSTALL_opts, quiet = FALSE,
                 keep_outputs = FALSE, ...)

... Arguments to be passed to download.file or to the functions for binary
installs on OS X and Windows (which accept an argument "lock": see the
section on ?Locking?).
#############################

Since only (...) were passed to the download.file, the quite parameter
specified in install.packages will not work for the download.file function.

*SOLUTION: *
To fix the bug, please
(1) to pass the quiet parameter to the download.file in the
install.packages function, or
(2) to use another variable name for the "quiet" option, so that users
can
decide the outputs of the download.file function when they install package.

Thank you very much.

Regards

Zhiqiu
