## Tune stratigraphic series to an astronomical target using graphical interface

### Description

Tune stratigraphic series to an astronomical target using graphical interface similar to Analyseries 'Linage' routine (Paillard et al, 1996).

### Usage

linage(dat,target,extrapolate=F,xmin=NULL,xmax=NULL,tmin=NULL,tmax=NULL,size=1,plotype=1,
output=1,genplot=T)


### Arguments

 dat Stratigraphic series for tuning, with two columns. First column is depth/height. target Astronomical tuning target series. First column is time. extrapolate Extrapolate sedimentation rates above and below 'tuned' interval? (T or F) xmin Minimum height/depth to plot. xmax Maximum height/depth to plot. tmin Minimum time value to plot. tmax Maximum time value to plot. size Multiplicative factor to increase or decrease size of symbols and fonts. plotype Type of plot to generate: 1= points and lines, 2 = points, 3 = lines output Return which of the following? 1 = tuned stratigraphic series; 2 = age control points; 3 = tuned stratigraphic series and age control points genplot Generate additional summary plots (tuned record, time-space map, sedimentation rates)? (T or F)

### Examples

 ## Not run:
# Check to see if this is an interactive R session, for compliance with CRAN standards.
# YOU CAN SKIP THE FOLLOWING LINE IF YOU ARE USING AN INTERACTIVE SESSION.
if(interactive()) {

# generate example series with 3 precession terms and noise using function 'cycles'
# then convert from time to space using sedimentation rate that increases from 1 to 7 cm/ka
ex=sedRamp(cycles(start=1,end=400, dt=2,noisevar=.00005),srstart=0.01,srend=0.07)

# create astronomical target series
targ=cycles(start=1,end=400,dt=2)

## manually tune
tuned=linage(ex,targ)

## should you need to flip the direction of the astronomical target series, use function 'cb':
tuned=linage(ex,cb(targ[1]*-1,targ[2]))

}

## End(Not run)
