plotly_radial

A function for producing interactive radial IVW and MR-Egger plots individually.The function utilises the output from the IVW_radial and egger_radial functions.

Usage

plotly_radial(r_object, TEST)

Arguments

r_object

An object of class "IVW" or "egger".

TEST

Logical; indicating whether testing the function

Value

A plotly object containing a radial plot of either the IVW or MR-Egger estimates. Hovering the mouse over individual datapoints will highlight the corresponding SNP identification number for that observation.
