Dear R help

Don't really understand if there is graph or should be graph.


> library(ggm)
Loading required package: graph
Error: package ?graph? could not be loaded
In addition: Warning messages:
1: package ?ggm? was built under R version 2.15.3 
2: In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc =
lib.loc) :
  there is no package called ?graph?

Hello,

The package 'ggm' depends on "graph", "igraph" and
"RGBL" packages.

The error message is clear: "there is no package called ?graph?"

Regards,
Pascal
