BWMR (Bayesian Weighted Mendelian Randomization), is an efficient statistical method to infer the causality between a risk exposure factor and a trait or disease outcome, based on GWAS summary statistics. 'BWMR' package provides the estimate of causal effect with its standard error and the P-value under the test of causality.
To install the development version of BWMR, it's easiest to use the 'devtools' package.
# install.packages("devtools")
library(devtools)
install_github("YangLabHKUST/BWMR")
The 'BWMR' vignette will provide a good start point for Mendelian randomization analysis using BWMR package. The main function is BWMR. You can find examples by running
library(ggplot2)
library(BWMR)
example(BWMR)
