Dear all,

I am trying to load a database, which name is in a variable (I actually ask the user to provide the name of the database he needs). Does any body know if this is even possible??

TaxonDatabaseKG <- "TxDb.Mmusculus.UCSC.mm10.knownGene"

TaxonDatabaseKG
[1] "TxDb.Mmusculus.UCSC.mm10.knownGene"

library(TaxonDatabaseKG)        # I'd like this to be similar as library(TxDb.Mmusculus.UCSC.mm10.knownGene)

I keep getting an error message:

Error in library(TaxonDatabaseKG) :  there is no package called ‘TaxonDatabaseKG’

Thanks for any help
