Since its initial publication, Statistical Methods for Reliability Data has remained a foundational text for analyzing time-to-failure (survival) data. Along with the first edition of the text, the authors provided an S-Plus software package, called SPLIDA (S-Plus LIfe Data Analysis), to help readers utilize the methods for industry data.
Today, R has supplanted S and S-Plus as the most popular statistical
computing language in the world. In response to this shift, Meeker began
an effort to translate SPLIDA into R under the name RSplida.
However, RSplida couldn’t be installed as a traditional R package and
was difficult to use with modern IDE’s. Freels partnered with Meeker to
restructure and modernize RSplida into this R package SMRD, with
the aim of publishing to the
CRAN.
As this package has not yet been published, you can install the latest
development version from GitHub: Note that RBuildtools will also need
to be installed on your machine.
if (packageVersion("devtools") < 1.6) {
install.packages("devtools")
}
devtools::install_github("Auburngrads/SMRD")Please note that this package is currently experimental and is under very active development. If you encounter any problems or unexpected behaviours, please create a new issue and include a reproducible example.
Once installed, the easiest way get started using SMRD is by checking
out the echapters. These are vignettes presenting example code and
results corresponding to what is shown in the each chapter of the 1st
edition of the SMRD text.
SMRD::echapter(chapter = 1)There are a number of tasks that need to be completed before publishing. These issues can be broken down into four main project areas. The links below show the current issues that exist within these areas.
