无法在R中加载ggplot2

Question

I'm having trouble loading ggplot2 using R version 2.12.1, as shown below. The only help I can find suggests loading "proto". I tried that and it didn't fix my problem. Any help would be very much appreciated. Thanks,

Hmmm, have you omitted some lines there, before the The downloaded packages are in.... ? I get:

Do you also see the * Done (ggplot2) message for example? If not, the installation likely failed for some reason and we need more details in order to help.
