%description
The 'Rcpp' package provides a C++ library to make it easier to use C++
with R. R and 'Rcpp' provide functions for a variety of statistical
distributions. Several R packages make functions available to R for
additional statistical distributions. However, to access these functions
from C++ code, a costly call to the R functions must be made. 'RcppDist'
provides a header-only C++ library with functions for additional
statistical distributions that can be called from C++ when writing code
using 'Rcpp' or 'RcppArmadillo'. Functions are available that return a
'NumericVector' as well as doubles, and for multivariate or matrix
distributions, 'Armadillo' vectors and matrices. 'RcppDist' provides
functions for the following distributions: the four parameter beta
distribution; the location- scale t distribution; the truncated normal
distribution; the truncated t distribution; a truncated location-scale t
distribution; the triangle distribution; the multivariate normal
distribution*; the multivariate t distribution*; the Wishart
distribution*; and the inverse Wishart distribution*. Distributions marked
with an asterisk rely on 'RcppArmadillo'.
