[BioC] Using htmlpage

[James W. MacDonald]

Hi John,

Thanks to some help from Martin Morgan (thanks Martin!), the devel 
version of annotate now has two additions.

1.) You can create links to Ensembl, using the repository 'ens'. Since 
AFAICT Ensembl requires a species to be part of the URI, you will have 
to pass an additional argument 'species' to htmlpage(). The form of this 
argument is species="Homo_sapiens" for e.g, Human. If you forget to pass 
the argument it will bomb out with an error.

This should work with ENSG, ENST, or ENSP identifiers, but let me know 
if you have problems.

2.) You can also now create links for arbitrary websites. There are 
three new functions, setRepository(), getRepositories() and 
clearRepository() that you can use to set up, look at, and remove 
repositories, respectively. This is all thanks to Martin - he makes 
smart use of an environment to hold the getQuery4XX() functions, and you 
can add new ones to the environment, thereby bypassing the namespace.

The function you add should have similar form to any of the 
getQuery4XX() functions. Just write up the function, and use 
setRepository() to put it into the environment. There are some examples 
in the help page for these functions that will hopefully get anyone 
interested in this started. Again, let me know if it is not clear, or if 
there are any problems.

Best,

Jim
