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

• data.frame 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))
