Provides function for RNA secondary structure plotting, comparison and module mining. Given a RNA secondary structure, you can obtain stem regions, hairpin loops, internal loops, bulge loops and multibranch loops of this RNA structure using this program. They are the basic modules of RNA secondary structure. For each module you get, you can use this program to label the RNA structure with a specific color. You can also use this program to compare two RNA secondary structures to get a score that represents similarity. Reference: Reuter JS, Mathews DH (2010) <doi:10.1186/1471-2105-11-129>.

Interface to access data via the United States Department of 
  Agriculture's National Agricultural Statistical Service (NASS) 'Quick Stats' 
  web API <https://quickstats.nass.usda.gov/api>. Convenience functions 
  facilitate building queries based on available parameters and valid parameter 
  values. This product uses the NASS API but is not endorsed or certified by NASS.

Facilitates mapping by making natural earth map data from <https://www.naturalearthdata.com/> more easily available to R users.

Vector map data from <https://www.naturalearthdata.com/>. Access functions are provided in the accompanying package 'rnaturalearth'.

Image data used as examples in the loon R package.

Use the <http://api.nbp.pl/> API through R. Retrieve
    currency exchange rates and gold prices data published by the
    National Bank of Poland in form of convenient R objects.

Provides the libraries of the EUtils operations for the
        RNCBI package.

Contains functions to retrieve, organize, and visualize weather data from the NCEP/NCAR Reanalysis (<http://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis.html>) and NCEP/DOE Reanalysis II (<http://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis2.html>) datasets.  Data are queried via the Internet and may be obtained for a specified spatial and temporal extent or interpolated to a point in space and time.  We also provide functions to visualize these weather data on a map.  There are also functions to simulate flight trajectories according to specified behavior using either NCEP wind data or data specified by the user.
