sim_gsd: Simulate a log-normal grain size distribution

Description Usage Arguments

Description

sim_gsd generates a log-normal grain size distribution for a user-specified D50. The user can also vary the spread of the distribution. The function returns a data frame containing the upper range of the size classes, the mid point of each size class, the proportion in each size class, and the cumulative proportion finer than the upper size class boundaries.

Usage

1
sim_gsd(D50, sp = 1, Map = FALSE)

Arguments

D50

median bed surface grain size (mm)

sp

(optional) spread of the distribution (default = 1)

Map

(optional) LOGICAL, when TRUE, the distribution is graphed
