Rhelp is a plain text mailing list. If your PhD program doesn't include 
training on how to use a mail client, then you should avail yourself of 
the online training that google offers. It is incredibly easy to sent 
plaintext messages with gmail.


You should always include your setup, preferably with the output of 
sessionInfor()


You should also include the full output of you console session ... not 
just the last line.


I just executed:

install.packages("semPlot")

... and got an error message saying the package "OpenMx" had failed to install properly. In the process of getting to that point there was a rather long list of package dependencies that were also installed. I'm on Linux and the install.packages function behaves differently here than it does on OSX or Windoze. There you should always include dependencies=TRUE in the parameters given to `install.packages`.

Since OpenMx failed to install., I decided to try again. Many times packages have dependencies which have dependencies which  ....  ... Turtles all the way down. Well, R only goes only turtle-level down.

OpenMv eventually compiles. It was the longest single package compilations I've ever seen. But finally I saw:

* DONE (OpenMx)

The downloaded source packages are in
	‘/tmp/Rtmp4ADe86/downloaded_packages’

# So I executed the install.packages again

> install.packages("semPlot")

Success.

Best of luck ... and do pay attention to the advice at the top. It's the only way to get beyond perpetual noobism.
