mr_funnel {MendelianRandomization}

Draw a funnel plot of variant-specific estimates

Description

The mr_funnel function draws a funnel plot of variant-specific causal estimates. Estimates (by/bx) are plotted against the precision of the estimates (abs(bx)/byse). Precision is the reciprocal of standard error. A vertical dashed line is plotted at the estimate from the mr_ivw function.

Usage

mr_funnel(object, CI = TRUE)

## S4 method for signature 'MRInput'
mr_funnel(object, CI = TRUE)

Arguments

object

An MRInput object.

CI

A logical variable dicating as to whether to plot the confidence interval associated with each point. Default value is TRUE.

Details

As the function produces a ggplot object, graphical parameters can be changed by adding commands from the ggplot2 package.

Examples

mr_funnel(mr_input(bx = ldlc, bxse = ldlcse, by = chdlodds, byse = chdloddsse))
