Combine all mr results

Description

This function combines results of mr(), mr_heterogeneity(), mr_pleiotropy_test() and mr_singlesnp() into a single data frame. It also merges the results with outcome study level characteristics in available_outcomes(). If desired it also exponentiates results (e.g. if the user wants log odds ratio converted into odds ratios with 95 percent confidence intervals). The exposure and outcome columns from the output from mr() contain both the trait names and trait ids. The combine_all_mrresults() function splits these into separate columns by default.

Usage

combine_all_mrresults(
  res,
  het,
  plt,
  sin,
  ao_slc = TRUE,
  Exp = FALSE,
  split.exposure = FALSE,
  split.outcome = FALSE
)

Arguments

`res`	Results from `mr()`.
`het`	Results from `mr_heterogeneity()`.
`plt`	Results from `mr_pleiotropy_test()`.
`sin`	Results from `mr_singlesnp()`.
`ao_slc`	Logical; if set to `TRUE` then outcome study level characteristics are retrieved from `available_outcomes()`. Default is `TRUE`.
`Exp`	Logical; if set to `TRUE` results are exponentiated. Useful if user wants log odds ratios expressed as odds ratios. Default is `FALSE`.
`split.exposure`	Logical; if set to `TRUE` the exposure column is split into separate columns for the exposure name and exposure ID. Default is `FALSE`.
`split.outcome`	Logical; if set to `TRUE` the outcome column is split into separate columns for the outcome name and outcome ID. Default is `FALSE`.
