mr_funnel: 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 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.
