seq.3vel {lorentz}R Documentation

seq method for three velocities

Description

Simplified version of seq() for three-velocities.

Usage

## S3 method for class '3vel'
seq(from, to, len, ...)

Arguments

from, to

Start and end of sequence

len

Length of vector returned

...

Further arguments (currently ignored)

Details

seq(a,b,n) returns a + t*(-b+a) where t is numeric vector seq(from=0,to=1,len=n).

This definition is one of several plausible alternatives, but has the nice property that the first and last elements are exactly equal to a and b respectively.

Examples


a <- as.3vel(c(4,5,6)/9)
b <- as.3vel(c(-5,6,8)/14)
x <- seq(a,b,len=9)

x[1]-a # should be zero
x[9]-b # should be zero


jj <- a + seq(0,1,len=9)*(b-a)

jj-x   # decidedly non-zero
