mpspline2

This package is a standalone re-implementation of GSIF::mpspline(), which applies a mass-preserving spline to soil attributes. Splining soil data is a safe way to make continuous down-profile estimates of attributes measured over discrete, often discontinuous depth intervals.

Installation

Install from CRAN with

install.packages('mpspline2')

Install from github with

devtools::install_github("obrl-soil/mpspline2")

Example

library(mpspline2)
dat <- data.frame("SID" = c( 1,  1,  1,  1),
                   "UD" = c( 0, 20, 40, 60),
                   "LD" = c(10, 30, 50, 70),
                  "VAL" = c( 6,  4,  3, 10),
                   stringsAsFactors = FALSE)
dat
spl_dat <- mpspline_tidy(obj = dat, var_name = 'VAL')
spl_dat$est_dcm
