[R] How to use msaPrettyPrint in memory efficient mode?

[Luigi Marongiu]

Hello,
I have an alignment made with the package MSA. I installed latex on my
ubuntu machine with
`sudo apt-get install texlive-full` but I could not find the package
texshade that is mentioned in the MSA's manual.
When I run msaPrettyPrint I get:
```

Looks like texshade has been installed but there is a problem with
memory. How can I set the memory limit for msaPrettyPrint?
