 Dear Uwe

Many thanks for your reply. I agree with you but I need the silencing of
output for a particular reason.

I am working on a statistical package called VOStat which uses a Java based
GUI to get the data and parameters of the test to be executed from the
user, creates the appropriate R script for it, runs it, and prints the
output given by R. For a particular test, if the required library is not
installed, the same is done dynamically without requiring any user input.
Now the problem I face is as follows:- Suppose the user requires a
correlation matrix of selected variables along with their p-values. For
this, I use the 'rcorr' function of the library 'Hmisc'. If the user does
not have 'Hmisc' available in his machine, it is automatically installed
for him. Once the installation is done, the library is loaded and 'rcorr'
is used for the necessary computation. But since I am presenting the entire
output generated by the R script (which has the install function as well),
along with the correlation matrices, the user of VOStat also gets to see
the output of 'install.packages()', something I want to avoid.

Could please suggest a workaround that could be used to get rid of the
output?

Thanks
Tejas

Hello!

Is there a way to suppress the output of 'install.packages()'? I have
seen that the 'download.file' function has a 'quiet' option but I do
not know how to use it.


I do not see any good reason to allow that. A user shoudl see if software
is being installed.
