RNA families (Rfam).


An object of class "InfoDataFrame" that contains information on RNA families (Rfam). This data is prepared based on ftp://anonymous@ftp.sanger.ac.uk/pub/databases/Rfam/11.0/database_files/rfam.txt.gz.




an object of class InfoDataFrame. It has slots for data and dimLabels:

  • data: a data.frame containing information about 2208 RNA families (in rows), with 3 columns ("id" for Rfam accession ID, and "level" always equals "Rfam", "description" for Rfam description)
  • dimLabels: a character describing labels for rows and columns in data
