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)
x |
A CalDates class object |
s |
Logical expression indicating dates to keep. The expression should include the term |
p |
Probability mass meeting the condition defined by |
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
A CalDates class object.
## 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)
