You can install the development version of TxDb.Ecoli.K12.MG1655
like so:
devtools::install_github('utubun/TxDb.Ecoli.K12.MG1655')
This is a basic example which shows you how to solve a common problem:
library(TxDb.Ecoli.K12.MG1655)
ecotx <- TxDb.Ecoli.K12.MG1655
# show the information related to the build
ecotx
# extract genes, as genomic ranges
gr <- GenomicFeatures::genes(ecotx)
# show extracted ranges
gr
# convert gene ID into transcript names
head(
(nm <- biomaRt::select(ecotx, names(gr), 'TXNAME', 'GENEID'))
)
methods(class = class(ecotx))
