In GJMeijer/soilmech: R functions and plots for Soil Mechanics teaching

Create polygons for each soil zone in Robertson's chart

Description

Generate polygons defined by (Frn, Qtn) points for each soil zone in Robertson's chart

Usage

robertson_polygons(nFr = 21, Fr_lim = c(0.1, 10), Qtn_lim = c(1, 1000))

Arguments

nFr	number of points on curved polygon edges. Fr interval is split linearly
Fr_lim	Fr lower and upper limit of plot
Qtn_lim	Qtn lower and upper limit of plot

Value

tibble with Fr (field 'Fr'), Qtn (field 'Qtn'), zone numbers (field 'zone') and soil descriptions (field 'soil')
