z_plot: Z plot

In jwr-git/mrpipeline: Implements a Ready-for-Use Mendelian Randomisation Pipeline

Z plot

Description

Creates a Z-score plot for SNPs, where Z = b / SE. This should follow a parabollic shape and so can be used to find certain SNPs which may not follow this shape. If 'plotly' is installed, the plot will be returned interactive.

Usage

z_plot(
  dat,
  snp_col = "SNP",
  beta_col = "beta.exposure",
  se_col = "se.exposure",
  pval_col = "pval.exposure",
  force_static = FALSE
)

Arguments

dat	A data.frame of data
snp_col	Column of SNP names (Optional)
beta_col	Column of MR beta estimates (Optional)
se_col	Column of standard errors for the beta estimates (Optional)
pval_col	Column of P values (Optional)
force_static	True for forcing the plot to be returned as a static plot (Optional)

Value
