Usage

mrmvinput_to_mvmr_format(dat)

Arguments

dat

Object from MendelianRandomization::mr_mvinput.

Value

Object of class mvmr_format, the MVMR format

Examples

if (require("MendelianRandomization", quietly = TRUE)) {
bx <- as.matrix(rawdat_mvmr[,c("LDL_beta", "HDL_beta")])
bxse <- as.matrix(rawdat_mvmr[,c("LDL_se", "HDL_se")])
dat <- MendelianRandomization::mr_mvinput(bx = bx,
                                          bxse = bxse,
                                          by = rawdat_mvmr$SBP_beta,
