Installation

You can install the released version of qMRI from CRAN with:

install.packages("qMRI")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("muschellij2/qMRI")

Example

This is a basic example which shows you how to solve a common problem:

library(qMRI)
#> Loading required package: awsMethods
#> 
#> Use the function setCores() to change the number of CPU cores.
