[R] [BioC] problem with biomaRt getHomolog function

[Kimpel, Mark William]

Steffen,

When the new biomaRt tries to load it errors out because I do not have
RMySQL installed. There is not a Windows binary for RMySQL and it does
contain C code that I do not know how to build.

I do not use the MySQL option in biomaRt. Does RMySQL need to be a
required dependency? Below is my screen output and sessionINfo.

require(biomaRt)
Loading required package: biomaRt
Loading required package: RMySQL
Error: package 'RMySQL' could not be loaded
In addition: Warning message:
there is no package called 'RMySQL' in: library(pkg, character.only =
TRUE, logical = TRUE, lib.loc = lib.loc)

Hi Mark,

I think the rat entrezgene id 613226 is a recently added entrezgene id 
and is not yet available in Ensembl.  Ensembl updates every two months 
and the last update of entrezgene id 613226 appears to be December 26 of

2006.  So this might be the reason.
Also I would suggest you use the developmental version of biomaRt 
(biomaRt_1.9.15) to do getHomolog queries.  A recent change in the 
BioMart suite enables the biomaRt package to retrieve both the id you 
use to query and the ids in the result of the query. 

Here's an example:

rat.entrezgene.ID=c("24842","83502","24205")
mouse.mart <- useMart("ensembl","mmusculus_gene_ensembl")
rat.mart<- useMart("ensembl", "rnorvegicus_gene_ensembl")
mouse.homolog<-getHomolog(id =rat.entrezgene.ID, from.mart = 
rat.mart,from.type = "entrezgene",to.type="entrezgene",
to.mart=mouse.mart)

 > mouse.homolog
     V1    V2
1 24842 22059
2 24205 11789
3 24205    NA
4 83502 12550

best,
Steffen
