[R] mysterious (to me) automatic loading of packages when R starts up

[Duncan Mackay]

Hello,
I have recently noticed that in one of my work areas, a number of packages
are automatically loaded without my explicitly requesting them to be loaded
(see below). This only happens in one particular workspace (located in a
folder). I suspect (without any real evidence) that this may be related to
my creating plots using the ggplot2 package earlier in this workspace.

I am running R 2.7.0 under Vista but I noticed the same behavior under R
2.6.2 last week.

Can someone please tell me why this is happening and how I can prevent this
automatic package loading in this workspace?

Thanks,
Duncan
