extract {astrochron}R Documentation

Extract record from EHA time-frequency output or eAsm output

Description

Extract record from EHA time-frequency output or eAsm output: Use interactive graphical interface to identify record.

Usage

extract(spec,get=NULL,xmin=NULL,xmax=NULL,ymin=NULL,ymax=NULL,h=6,w=4,ydir=1,pl=0,
        ncolors=100,genplot=T,verbose=T)

Arguments

spec

Time-frequency spectral results to evaluate, or alternatively, eAsm results to evaluate. For time-frequency results, must have the following format: column 1=frequency; remaining columns (2 to n)=power, amplitude or probability; titles for columns 2 to n must be the location (depth or height). Note that this format is ouput by function eha. For eAsm results, must have the following format: column 1=sedimentation rate; remaining columns (2 to n)=Ho-SL or ASM; titles for columns 2 to n must be the location (depth or height).

get

Record to extract (height/depth/time). If no value given, graphical interface is activated.

xmin

Minimum frequency or sedimentation rate for PLOTTING.

xmax

Maximum frequency or sedimentation rate for PLOTTING.

ymin

Minimum depth/height for PLOTTING.

ymax

Maximum depth/height for PLOTTING.

h

Height of plot in inches.

w

Width of plot in inches.

ydir

Direction for y-axis in plots (depth or height). -1 = values increase downwards (slower plotting!), 1 = values increase upwards.

pl

An option for the color plots (0=do nothing; 1=plot log of value [useful for plotting power], 2=normalize to maximum value [useful for plotting amplitude]).

ncolors

Number of colors to use in plot.

genplot

Generate summary plots? (T or F)

verbose

Verbose output? (T or F)
