Arguments

data

The distributions to be plotted, either a matrix of columns or as a list (see examples below).

ages

The ages in millions of years for each box to be plotted.

units

The temporal unit(s) to be included in the timescale, options include: "Eon", "Era", "Period", "Epoch", "Age" and "User". The option "User" is required when including a user-defined timescale. This also requires an object to be assigned to user.scale.

tick.scale

The resolution of the tick marks at the base of the timescale, the default is the same as units. The resolution of the scale can also be chosen by specifiying a value or removed entirely by using "no".

boxes

Option to include grey boxes for individual time bins. Same options as for scale.

abbrev

Option to abbreviate names of geological units in the time scale, options are the same as for units.

cex.age

Size of the numbers on the scale bar.

cex.ts

Size of the text in the time scale.

cex.pt

Size of the individual points.

age.lim

The range of values for the x-axis.

data.lim

The range of values for the y-axis.

box.width

The width of the boxes in millions of years.

user.scale

The data object to be used when including a user-defined time scale, requires the option "User" to be included in units. See data(UKzones) as an example of the required data format.

ts.col

Whether to include colours in the timescale.

ts.width

Proportion of the plot used for the time scale, value must be between 0 and 1.

label

Label for the y-axis.

vers

The version of the time scale to use. Options include: "ICS2015","ICS2014","ICS2013","ICS2012","ICS2010","ICS2009" or "ICS2008".

no.axis

Option to remove the label on the y-axis.

notch

Option to draw notches in the individual boxes, see help(boxplot).

log

Option to plot the y-axis on a log scale, default is FALSE.

color

Option for the color of the boxes.

direction

The orientation of the plot, can be either "horizontal" or "vertical".

erotate

A numerical value for the rotation for the Epoch/Series temporal units, default values are 0 when direction = "upwards" and 90 when direction = "rightwards".

arotate

A numerical value for the rotation for the Age/Stage temporal units, default values are 0 when direction = "upwards" and 90 when direction = "rightwards".

urotate

A numerical value for the rotation for the User temporal units, default values are 0 when direction = "upwards" and 90 when direction = "rightwards".

...

All other options passed to points.

## Plotting data from a matrix

 data1 <- matrix(ncol=10,nrow=30,data=runif(30,0,100))
  ages <- seq(10,100,10)
    geoscaleBox(data1,ages,boxes="Age",pch=19,box.width=2)    

## Plotting data from a list
 
 data2 <- vector("list",10)
  for(d in 1:length(data2)){
  	data2[[d]] <- runif(30,0,100)
  }
	ages <- seq(10,100,10)
     geoscaleBox(data2,ages,boxes="Age",pch=19,box.width=2)    

## Example dataset

 data(size)
  ages <- as.numeric(colnames(size))
   geoscaleBox(data=size,ages=ages,pch=19,boxes="Age")

# Plotting on a log scale
   geoscaleBox(data=size,ages=ages,pch=19,boxes="Age",log=TRUE)
