MRPracticals

The MRPracticals R package provides necessary information for MR course practical sessions. It requires R version 3.5 and R Studio to be installed, as well as Rtools which is available at https://cran.r-project.org/bin/windows/Rtools/ for processing vignette files. It is also necessary to have a google account for MR Base authorisation.

Information for two separate pratical sessions is currently included, pertaining to:

1. MR Base
2. The RadialMR package
3. The MVMR package

Installation

To install MRPracticals directly from the GitHub repository, first make sure you have R version 3.5 or higher, R Studio, and R Tools version 3.5 installed.

Next, open R Studio and install the devtools, knitr, and rmarkdown packages:

install.packages(c("devtools", "knitr", "rmarkdown"))

Next, we need to install the TwoSampleMR and MRInstruments R packages from Github.

library(devtools)
install_github(c("MRCIEU/TwoSampleMR","MRCIEU/MRInstruments"))

Then the MRPracticals package can be installed using:

library(devtools)
install_github("WSpiller/MRPracticals",build_opts = c("--no-resave-data", "--no-manual"),build_vignettes = TRUE)

To update the package just run the install_github("WSpiller/MRPracticals", build_opts = c("--no-resave-data", "--no-manual")) command again.

Description

1. Running the command vignette("MRBase") will display a document giving a detailed description of the MR Base practical.

2. Running the command vignette("RadialMR") will display a document giving a detailed description of the RadialMR practical.
