Generate random data sets (wakefield)
wakefield is designed to quickly generate random data sets. The user passes n (number of rows) and predefined vectors to the r_data_frame function to produce a dplyr::tbl_df object.
An Interface to the NOAA Operational Model Archive and Distribution System (rNOMADS)
An interface to the National Oceanic and Atmospheric Administration’s Operational Model Archive and Distribution System (NOMADS) that allows R users to quickly and efficiently download global and regional weather model data for processing. rNOMADS currently supports a variety of models ranging from global weather data to an altitude of 40 km, to high resolution regional weather models, to wave and sea ice models. It can also retrieve archived NOMADS models. rNOMADS can retrieve binary data in grib format as well as import ascii data directly into R by interfacing with the GrADS-DODS system.
Matrix exponential (expm)
Computation of the matrix exponential and related quantities.
