Authors@R: person("Jonas", "Förster", email = "jonasfoerster@gmail.com", role = c("aut", "cre"))
Check if an 'externalptr' is a null pointer.
R does currently not have a native function for that purpose.
This package contains a C function that returns TRUE in case of a null pointer.

Title: Isotonic Regression on Survival Analysis
Description: Nonparametric estimation on survival analysis under order restrictions. It estimates monotone increasing or decreasing covariate effects in the proportional hazards model. Yunro Chung et al. (2018) <doi:10.1093/biomet/asx064>.

Title: Discovery, Retrieval, and Analysis of Water Isotope Data
Authors@R: person("Gabe", "Bowen", email = "gabe.bowen@utah.edu",
Description: The wiDB...() functions provide an interface to the public API
build, check and submit queries, and receive and
unpack responses. Data analysis functions support Bayesian
inference of the source and source isotope composition of water
samples that may have experienced evaporation. Algorithms
