which.CalDates function

Which indices for calibrated dates

Gives the TRUE indices of calibrated dates (CalDates class object) based on Logical expressions of time intervals.

which.CalDates(x, s, p)

Arguments

• x: A CalDates class object
• s: Logical expression indicating dates to keep. The expression should include the term BP which refers to specific dates.
• p: Probability mass meeting the condition defined by ss.

Returns

A CalDates class object.

Details

The function subsets CalDates class objects by identifying all dates that have a probability mass larger than p for a user defined logical expression of temporal interval containing the term BP, where BP refers to radiocarbon date. See examples for further detailes

Examples

## Generate some calibrated dates
x = calibrate(c(12100,5410,5320,3320),errors=c(20,20,30,30))
## Subsets all dates that have a probability mass above 0.8 before 10000 BP
x2 = which.CalDates(x,BP>10000,p=0.8)
## Subsets all dates that have a probability mass above 0.5 between 6000 and 6300 BP
x3 = which.CalDates(x,BP>6000&BP<6300,p=0.5)
