[R] Need help installing qtoolbox

[Toby Popenfoose]

I have windows version of R v1.6.2

I have downloaded the qtoolbox.zip from
 http://www.cmis.csiro.au/S-PLUS/qtoolbox/

My R command line is
> install.packages("C:/Program Files/R/qtoolbox.zip", .libPaths()[1], CRAN =
NULL)

and I get the following error message:
updating HTML package descriptions
Warning message:
error -1 in extracting from zip file
>

Is there another way to install this S-Plus based Package?  Is there another
control chart library for R that I should be trying instead?

Thank you,
