Hi all.

I recently found out about JGR and loved it! However, for some reason
JGRstopped working corrrectly on my Intel Mac
10.4.9 running R 2.5 and I have no idea why. Furthermore, iplots will not
install (but for a while JGR still ran fine).

In JGR when I type in a command the command is pasted from the bottom part
of the console to the top part, but nothing is returned. For example:

> mean(1:5)
>

Notice that the result is not returned. However, when I define mean(1:5) as
an object, say x, then in the object browser the object is listed with its
correct value ( i.e., 3 in this example). Why is JGR not printing the result
as expected and as it did previously -  It is performing the calculations?

Separately, iplots will not install. After using the install binarys feature
from within R and from downloading from CRAN, everything appears to go fine
until I try to load the package. I also specified to install dependencies.
In the check on CRAN the results for Mac have a *, implying "Results with
[*] or [**] were obtained by checking with --install=fake and --install=no,
respectively" but I'm not sure what that means. Here is what happens when I
install the package from source:

So, everything looks good. When I load the package here is what happens

While JGR worked I like it. I also removed and reinstalled JGR.

Have a good day,
Ken
