[R] trouble loading ggplot2 using R

[R. Michael Weylandt]

Alternatively, the OP might just use set.seed(1) to get a fresh seed
rather than playing with .Random.seed directly.

To the OP: if you're on Mac, follow these instructions and we'll see
if that fixes your problem:

**) open Terminal
**) type R -q --vanilla
**) At the prompt type the following lines

set.seed(1)
install.packages("ggplot2")
library("ggplot2")
qplot(carat, price, data = head(diamonds, 200)) # Should make a nice
ggplot graph with not so many dots

**) If that works and you don't have anything important saved in your
default start up, return to Terminal and type

mv .RData .Trash

(This just puts it in the trash so we can recover it if you realize
later there actually is something important there)

**) Then start R by typing "R -q" and enter

library("ggplot2")
qplot(carat, price, data = head(diamonds, 200))

and that should work.

Hopefully that will isolate your problem. If anything fails along the
way, let us know exactly where and how.

Best,
Michael
