R-package for interpretable nonparametric modeling of longitudinal data using additive Gaussian processes. Contains functionality for inferring covariate effects and assessing covariate relevances. Various models can be specified using a convenient formula syntax.
See overview, tutorials, vignettes and documentation at https://jtimonen.github.io/lgpr-usage/index.html.
- The package should work on all major operating systems.
- R 3.4 or later is required, R 4.0.2 or later is recommended
- The latest released version that is available from CRAN can be installed simply via
install.packages("lgpr")Installing from CRAN is probably the easiest option since they might have binaries for your system (so no need to build the package from source yourself).
- The latest released version (which might not be in CRAN yet) can be installed via
install.packages('devtools') # if you don't have devtools already
devtools::install_github('jtimonen/lgpr', build_vignettes = TRUE)- The latest development version can be installed via
devtools::install_github('jtimonen/lgpr', ref = "develop")Github installations are source installations (they require a C++ compiler).
- If you have trouble installing the dependency rstan, see these instructions
- Installing from source requires that you have your toolchain setup properly. See the instructions for:

data is also provided there. See also the built-in read_proteomics_data() function.
