Soil texture class to texture fractions conversion

Description

Soil texture class to texture fractions conversion

Usage

TT2tri(
  TT.class,
  se.fit = TRUE,
  TT.im = NULL,
  soil.var = "TEXMHT",
  levs = c("S", "LS", "SL", "SCL", "SiL", "SiCL", "CL", "L", "Si", "SC", "SiC", "C",
    "HC")
)

Arguments

TT.class	based on the soiltexture package
se.fit	derive errors
TT.im	soil texture triangle image
soil.var	column name in the TT.im file
levs	texture class legends (USDA system)

Value

Data frame with estimated sand, silt and clay values

Examples

library("plyr")
## convert textures by hand to sand, silt and clay:
TEXMHT <- c("CL","C","SiL","SiL","missing")
x <- TT2tri(TEXMHT)
x
