TwoSampleMR 0.6.21

• Fixed typos in Steiger related documentation (thanks to @eleanorsanderson and Kaitlin Wade for providing the motivating example for this).
• Some code cleanup to make debugging easier.
• Reduced size of installed package by removing some unused files.

TwoSampleMR 0.6.20

• TwoSampleMR now requires ieugwasr version 1.1.0 which provides improved error messages.
• Changed error handling - now if the API gives an error code it is propagated as an error with message in TwoSampleMR.
• Headers sent to API are updated.

TwoSampleMR 0.6.19

• Further fixes for the forthcoming version 4 of ggplot2.

TwoSampleMR 0.6.18

• Fixes to mr_forest_plot(), forest_plot_1_to_many(), mr_leaveoneout_plot(), and mr_scatter_plot() for compatibility with the forthcoming release of version 4 of ggplot2.
• Made some minor improvements in the Perform MR vignette including adding back several of the forest plots.

TwoSampleMR 0.6.17

• Continued amends to the plot for MR-GRIP (thanks @fdudbridge)

TwoSampleMR 0.6.16

• Added weak instrument adjustment estimate and intercept to returned output of mr_grip() (thanks @fdudbridge)
• Amended mr_scatter_plot() to issue a message about the scale the MR-GRIP estimate is plotted on (thanks @fdudbridge)

TwoSampleMR 0.6.15

• Bumped the minimum required version of R to 4.1.0. This is due to a dependency (the scales package) of a dependency (the ggplot2 package), which now has this requirement.

TwoSampleMR 0.6.14

• Minor amends to the mr_grip() returned object names (thanks @fdudbridge)
• Fixed some typos in the helpfiles and vignettes

TwoSampleMR 0.6.13

• Added mr_grip() function which implements the MR-GRIP (modified MR-Egger with the Genotype Recoding Invariance Property) method of Dudbridge and Bowden et al. (2025).
  The new method can be accessed by mr(dat, method_list = "mr_grip") or it can be added to the default list of methods with mr(dat, method_list = c(subset(mr_method_list(), use_by_default)$obj, "mr_grip")).
• Added Pub Med IDs for more of the methods.
• The format_data() function no longer causes a stack overflow when its dat argument is not a variable (thanks to @DarwinAwardWinner)

TwoSampleMR 0.6.12

• Fixed a bug in format_data() (thanks to @lea-urpa)
• For MVMR data extraction in mv_extract_exposures() and mv_extract_exposures_local(), SNPs that do not pass harmonisation between exposures in MVMR are now dropped (thanks @yatest)
• The comments about mr.raps in the Perform MR vignette have been updated
