[R] R GUI in Ubuntu?

[Andy Weller]

OK, so I did:
sudo R CMD javareconf

followed by the following in R as root:
install.packages("JGR",dep = TRUE)

which I think went OK because if I do:
library()

then JGR is listed. From the terminal:
"Packages in library '/usr/local/lib/R/site-library':

JavaGD                  Java Graphics Device
JGR                     JGR - Java Gui for R
rJava                   Low-level R to Java interface"

BUT, if I then run:
JGR()

then I get:
Error: could not find function "JGR"

I am confused...?!?

Thanks in advance, Andy
