granplot: Histogram with a cumulative percentage curve

In G2Sd: Grain-size Statistics and Description of Sediment

Description

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

Usage

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

Arguments

x	A numeric matrix or data frame (see the shape of data(granulo))
xc	Define a column
hist	If TRUE, display a histogram; if FALSE, do not display a histogram
cum	If TRUE, display a cumulative percentage curve; if FALSE do not display a cumulative percentage curve
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	logical. Should the sort order be increasing or decreasing?

Details

The obtained graph is the most commonly used by Sedimentologists
