R version of the 'InterVA5' software (http://www.byass.uk/interva) for coding cause of death from verbal autopsies. It also provides simple graphical representation of individual and population level statistics.
This is an R package replicating InterVA-5 software. For stable version of the package please visit http://cran.r-project.org/web/packages/InterVA5/index.html. R can be downloaded and installed from https://cran.r-project.org/.
If you have any questions regarding this package, or have concerns/find bugs/have new ideas in better implementations to share, please contact Richard Li at lizehang@uw.edu.
To install the package from CRAN, run the script:
install.packages("InterVA5")Here is an example session of how to use the InterVA5 with the example data set:
> library(InterVA5)
> data(RandomVA5)
> ## assign caueses
> sample_output <- InterVA5(Input = RandomVA5, HIV = "h", Malaria = "v", write=TRUE,
directory = tempdir(), filename = "VA5_result")
