Description

Organises the summary level data for use in the Bayesian MR functions

Usage

mr_format(rsid, xbeta, ybeta, xse, yse)

Arguments

rsid	A vector of genetic variants used for analysis, if unspecified a vector is automatically generated.
xbeta	A numeric vector of the instrument-phenotype associations.
ybeta	A numeric vector of the instrument-outcome associations.
xse	The standard errors of the instrument-phenotype associations xbeta.
yse	The standard errors of the instrument-outcome associations ybeta.

Value

A formatted data frame for analysis of class mr_format.

Examples

data(bmi_insulin)
dat <- mr_format(rsid = bmi_insulin[,"rsid"],
          xbeta = bmi_insulin[,"beta.exposure"],
          ybeta = bmi_insulin[,"beta.outcome"],
          xse = bmi_insulin[,"se.exposure"],
          yse = bmi_insulin[,"se.outcome"])
class(dat)
