1 Introduction
The Organism.dplyr creates an on disk sqlite database to hold data of an organism combined from an ‘org’ package (e.g., org.Hs.eg.db) and a genome coordinate functionality of the ‘TxDb’ package (e.g., TxDb.Hsapiens.UCSC.hg38.knownGene). It aims to provide an integrated presentation of identifiers and genomic coordinates. And a src_organism object is created to point to the database.
The src_organism object is created as an extension of src_sql and
src_sqlite from dplyr, which inherited all dplyr methods. It also
implements the select() interface from AnnotationDbi and
genomic coordinates extractors from GenomicFeatures.
2 Constructing a src_organism
2.1 Make sqlite datebase from ‘TxDb’ package
The src_organism() constructor creates an on disk sqlite database file with
data from a given ‘TxDb’ package and corresponding ‘org’ package. When dbpath
is given, file is created at the given path, otherwise temporary file is
created.
library(Organism.dplyr)Running src_organism() without a given path will save the sqlite file to a
tempdir():
src <- src_organism("TxDb.Hsapiens.UCSC.hg38.knownGene")Alternatively you can provide explicit path to where the sqlite file should be saved, and re-use the data base at a later date.
path <- "path/to/my.sqlite"
src <- src_organism("TxDb.Hsapiens.UCSC.hg38.knownGene", path)supportedOrganisms() provides a list of organisms with corresponding ‘org’
and ‘TxDb’ packages being supported.

## # … with 11 more rows2.2 Make sqlite datebase from organism name
Organism name, genome and id could be specified to create sqlite database. Organism name (either Organism or common name) must be provided to create the database, if genome and/or id are not provided, most recent ‘TxDb’ package is used.
src <- src_ucsc("human", path)2.3 Access existing sqlite file
An existing on-disk sqlite file can be accessed without recreating the database. A version of the database created with TxDb.Hsapiens.UCSC.hg38.knownGene, with just 50 Entrez gene identifiers, is distributed with the Organism.dplyr package

Methods select(), keytypes(), keys(), columns() and mapIds from
AnnotationDbi are implemented for src_organism objects.
Use keytypes() to discover which keytypes can be passed to keytype argument
of methods select() or keys().

src_organism object.

## [46] "tx_type" "uniprot"keys() returns keys for the src_organism object. By default it returns the
primary keys for the database, and returns the keys from that keytype when the
keytype argument is used.

keys columns and keytype arguments. If requested columns that have multiple
matches for the keys, select_tbl() will return a tibble with one row for
each possible match, and select() will return a data frame.

Eleven genomic coordinates extractor methods are available in this
package: transcripts(), exons(), cds(), genes(),
promoters(), transcriptsBy(), exonsBy(), cdsBy(),
intronsByTranscript(), fiveUTRsByTranscript(),
threeUTRsByTranscript(). Data can be returned in two versions, for
instance tibble (transcripts_tbl()) and GRanges or GRangesList
(transcripts()).
Filters can be applied to all extractor functions. The output can be resctricted
by an AnnotationFilter, an AnnotationFilterList, or an expression that can
be tranlated into an AnnotationFilterList. Valid filters can be retrieved by
supportedFilters(src).
