So for example, if the inparanoid package is the human package, then the hom.Rn.inpRATNO map would provide mappings between human and rat. } \details{ Mappings between gene identifiers and their paralogs as predicted by the Inparanoid algorithm. The map filters out paralogs that have an Inparanoid score less than 100%. Mappings are normally given from the ID of the organism in the package to the IDs of the organism listed in the map name. Reversal can be made of ANY map by using the function revmap (see examples below). Names for these maps are done in the "INPARANOID style" which means that they are normally the 1st three letters of the genus followed by the 1st two letters of the species. For example: "Mus musculus" becomes "MUSMU", "Homo sapiens" becomes "HOMSA", "Monodelphis domestica" becomes "MONDO" etc. This means that for most of these organisms it will be possible to easily guess the abbreviations used. An exception may occur in the future if a new model organism has a very similar genus and species name to an existing one. } \references{ \url{http://inparanoid.sbc.su.se/download/current/sqltables} } \examples{ x <- hom.Rn.inpAPIME # Get honeybee IDs that are paralogous to the pkg IDs mapped_IDs <- mappedkeys(x) # Convert to a list xx <- as.list(x[mapped_IDs]) if(length(xx) > 0) { # Get the paralogs for the first five genes xx[1:5] # Get the first one xx[[1]] } #Now for the reverse map (honeybee IDs back to pkg paralog) x <- revmap(hom.Rn.inpAPIME) mapped_IDs <- mappedkeys(x) # Convert to a list xx <- as.list(x[mapped_IDs]) if(length(xx) > 0) { # Get the paralogs for the first five IDs xx[1:5] # Get the first one xx[[1]] } \dontrun{ #For the most common organisms, we try to ensure that you can #map back to an Entrez Gene ID by providing you with necessary #maps in the related organism based annotation packages.
