Usage

iso(dat,xmin,xmax,col=2,logx=F,logy=F,genplot=T,verbose=T)

Arguments

dat

Data frame containing stratigraphic variable(s) of interest. First column must be location (e.g., depth).

xmin

Minimum depth/height/time for isolation. If xmin is not specified, it will be selected using a graphical interface.

xmax

Maximum depth/height/time for isolation. If xmax is not specified, it will be selected using a graphical interface.

col

If you are using the graphical interface to select xmin/xmax, which column would you like to plot? (default = 2).

logx

Plot x-axis using logarithmic scaling? (T or F)

logy
