Calculate root accumulation

Calculate root accumulation

Usage

root_accumulation(x, group, depth, variable, stdrz = "counts")

Arguments

x

Data frame containing group, depth, and variable columns

group

Character vector specifying grouping variable(s)

depth

Character string specifying depth column name

variable

Character string specifying accumulating values column

stdrz

Character string specifying standardization method

Value

Numeric vector of accumulated values

Examples

df = data.frame(depth = c(seq(0,80,20),seq(0,80,20)),
               Plot = c(rep("a",5),rep("b",5)), rootpx = c(5,50,20,15,5,10,40,30,10,5) )
accum_root = root_accumulation(df,group = "Plot", depth = "depth", variable = "rootpx")
