                        Changes in version 0.4.7                        

  - pleiotropy_rmvmr(), plot_rmvmr() and strength_rmvmr() no longer pass
    on the warning from RadialMR 1.2.5 and later that the fixed-effect
    exact confidence interval of RadialMR::ivw_radial() is empty. RMVMR
    does not use that interval, so the warning, which was repeated for
    each exposure, was not relevant. Results are unchanged.
  - Now requires RadialMR 1.2.5 or later.

                        Changes in version 0.4.6                        

  - Fixed a bug in the corrected Q-statistic calculation used by
    pleiotropy_rmvmr() and plot_rmvmr(): the square-root radial weight
    Wj was not squared, so SNP contributions were weighted by the
    square-root weight rather than the full inverse-variance weight.
    Q-statistics, their p-values and outlier detection now differ from
    previous versions (thanks @nvitt, #8).

                        Changes in version 0.4.5                        

  - Fixed a bug in strength_rmvmr() where supplying gencov as a matrix
    or vector (rather than the scalar default) errored before
    MVMR::strength_mvmr() was called.
  - format_rmvmr() now generates placeholder variant IDs when RSID =
    NULL, matching the documentation. The RSID argument description
    previously showed a typo (RSID="NULL").
  - plot_rmvmr() no longer recomputes the univariate radial analyses
    when called with the default cordat = NULL, roughly halving the
    number of RadialMR::ivw_radial() calls. Results are unchanged.
  - ivw_rmvmr() now fits the radial IVW model explicitly rather than via
    variables left over from the orientation loop. The estimate is
    invariant to the choice of orientation, so this is fitted directly
    as the canonical model; the returned coefficients (estimates,
    standard errors, t-values and p-values), residual standard error and
    degrees of freedom are unchanged.
  - ivw_rmvmr() no longer returns the undocumented data element. This
    element held intermediate orientation data frames that were not used
    elsewhere in the package. The estimated coefficients remain
    unchanged and are still available in the coef element.

                        Changes in version 0.4.4                        

  - Bump roxygen2 to 8.0.0 and add a package level helpfile.

                        Changes in version 0.4.3                        

  - Implement some code optimizations.

                        Changes in version 0.4.2                        

  - RMVMR now requires MVMR version 0.4.3 or later.

                        Changes in version 0.4.1                        

  - Fixed a bug in plot_rmvmr() in the ggplot2::scale_x_continuous()
    calls. RMVMR should now run under version 4 of ggplot2, which is due
    to be released soon.

                         Changes in version 0.4                         

  - RMVMR now required R 4.1.0 or newer. This is because of the
    requirement of a dependency package of ggplot2, the scales package,
    now having this requirement (which is the new tidyverse requirement
    on release of R 4.5.0).
