rtimes: Relative times

Description

Relative times from 1 to the number of observed years are computed. Duplicated times can be sinchronized by replacing unique values with NA.

Usage

rtimes(x, only.dup = TRUE)

Arguments

x

numeric vector with names representing the formation years, or multilevel data frame containing a column of years.

only.dup

logical. Extract only duplicated times. If TRUE then unique times are replaced with NA. If all computed times are unique then this argument is ignored.

Value

object with the initial vector and its formation times.

Examples

## row names of a vector
fy <- function(y,span){(y - span):y}
x <- c(fy(2005,5),fy(2007,10)) 
## (not run) Simulating the vector
r <- abs(rnorm(length(x)))
names(r) <- x
## (not run) computing relative times:
rtimes(r,only.dup = TRUE)        
## (not run) Extracting only duplicated times:
na.omit(rtimes(r,only.dup = TRUE))
