A New Perspective on Early Settlements

Current Key Intersections between Theoretical and Computational Archaeology

era v0.6.0 is now available on CRAN: install.packages("era") library(era) This minor release adds functions for chronological comparison of year vectors: x <- yr(c(200, 100, 300), "BCE") yr_earlier_than(x, yr(150, "BCE")) #> # BCE years : #> [1] FALSE FALSE TRUE #> # Era: Before Common Era (BCE): Gregorian years (365.2425 days), counted backwards from 1 yr_later_than(x, yr(150, "BCE")) #> # BCE years : #> [1] TRUE FALSE FALSE #> # Era: Before Common Era (BCE): Gregorian years (365.2425 days), counted backwards from 1 And for calculating chronological differences between year vectors: yr_difference(yr(300, "BCE"), yr(100, "BCE")) #> # years : #> [1] 200 #> # Era: Gregorian years (365.2425 days) These functions are aware of era directionality: “BCE” years count backwards, so 300 BCE is earlier than 100 BCE. They support work on tempo, a new package I am working on that represents chronological intervals and the temporal relations between them.
