pseval: Methods for Evaluating Principal Surrogates of Treatment Response
Installation
pseval is an R package aimed at implementing existing methods for surrogate evaluation using a flexible and common interface. Development will take place on the Github page, and the current version of the package can be installed as shown below. First you must install the devtools package, if you haven't already install.packages("devtools").
devtools::install_github("sachsmc/pseval")Check out the vignette for methodological details and information on how to use the package.
Check out the cheat sheet for a quick reference.
