granplot: Histogram with a cumulative percentage curve

In G2Sd: Grain-Size Statistics and Description of Sediment

Histogram with a cumulative percentage curve

Description

This function provides a histogram of the grain-size distribution with a cumulative percentage curve

Usage

granplot(x, xc = 1, meshmin=1, hist = TRUE, cum = TRUE, main = "", 
			col.cum = "red", col.hist="darkgray", cexname=0.9,
			cexlab=1.3, decreasing=FALSE, log.scale=TRUE)

Arguments

x	A numeric matrix or data frame (see the shape of data(granulo))
xc	A numeric value or a numeric vector to define columns
meshmin	Define the size of the smallest meshsize if it is 0 in raw data
hist	If TRUE, display a histogram; if FALSE, do not display a histogram (only for only one column)
cum	If TRUE, display a cumulative percentage curve; if FALSE do not display a cumulative percentage curve (only for only one column)
main	Add a title to the current plot
col.cum	Color in which cumulative percentage curve will be drawn
col.hist	Color in which histogram will be drawn
cexname	A numerical value giving the amount by which plotting text and symbols should be magnified relative to the default.
cexlab	A numerical value giving the amount by which axis labels should be magnified relative to the default.
decreasing	A logical value defining the order increasing or decreasing
log.scale	A logical value; if TRUE (default), use logarithmic scale for x-axis; if FALSE, use linear scale

Details

The obtained graph is the most commonly used by Sedimentologists

Value

A histogram with a cumulative percentage curve
