Today dqrng version 0.3.1 made it unto CRAN and is now propagating to the mirrors. Kyle Butts provided the implementation for the new dqrrademacher method for drawing Rademacher weights. The Rademacher distribution is equivalent to flipping a fair coin... [Read more...]

This morning swephR version 0.3.1 made it unto CRAN and is now propagating to the mirrors. The goal of swephR is to provide an R interface to the Swiss Ephemeris (SE), a high precision ephemeris based upon the DE431 ephemeris from NASA’s JPL. It ... [Read more...]

Yesterday tikzDevice version 0.12.4 made it unto CRAN and is now propagating to the mirrors. The tikzDevice package provides a graphics output device for R that records plots in a LaTeX-friendly format. The device transforms plotting commands issued b... [Read more...]

Today dqrng version 0.3.0 made it unto CRAN and is now propagating to the mirrors. This release contains a breaking change: The initial state of dqrng’s RNG is based on R’s RNG, which used to advance R’s RNG state. The implementation... [Read more...]

This afternoon swephR version 0.3.0 made it unto CRAN and is now propagating to the mirrors. The goal of swephR is to provide an R interface to the Swiss Ephemeris (SE), a high precision ephemeris based upon the DE431 ephemeris from NASA’s JPL. It covers the time range 13201 BCE to 17191 ...

Yesterday tikzDevice version 0.12.3 made it unto CRAN and is now propagating to the mirrors. The tikzDevice package provides a graphics output device for R that records plots in a LaTeX-friendly format. The device transforms plotting commands issued by R functions into LaTeX code blocks. When included in a paper typeset ... [Read more...]

In a previous post I have shown that without intervention RcppNumerical does not handle integration over infinite ranges. In this post I want to generalize the method to integrals where only one of the limits is infinite. In addition, I want to make it more user friendly, since I would ... [Read more...]
