sharpshootR

This package contains a mish-mash of functionality and sample data related to the daily business of soil survey operations with the USDA-NRCS. Many of the functions are highly specialized and inherit default arguments from the names used by the various NCSS (National Cooperative Soil Survey) databases.

Examples 

library(sharpshootR)
library(aqp)
data(loafercreek, package = 'soilDB')

# generalize horizon names using REGEX rules
n <- c('Oi', 'A', 'BA','Bt1','Bt2','Bt3','Cr','R')
p <- c('O', '^A$|Ad|Ap|AB','BA$|Bw', 
       'Bt1$|^B$','^Bt$|^Bt2$','^Bt3|^Bt4|CBt$|BCt$|2Bt|2CB$|^C$','Cr','R')
loafercreek$genhz <- generalize.hz(loafercreek$hzname, n, p)

# remove non-matching generalized horizon names
loafercreek$genhz[loafercreek$genhz == 'not-used'] <- NA
loafercreek$genhz <- factor(loafercreek$genhz)

# aggregate color data, this function is from the `aqp` package
a <- aggregateColor(loafercreek, 'genhz', k = 8)

# plot
par(mar=c(4.5, 1.25, 1, 0.25))
aggregateColorPlot(a, print.n.hz = TRUE)
