seq: seq method for three velocities

Description Usage Arguments Details Author(s) Examples

Simplified version of seq() for three-velocities.

1 2	## S3 method for class '3vel' seq(from, to, len, ...)

`from,to`	Start and end of sequence
`len`	Length of vector returned
`...`	Further arguments (currently ignored)

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 the a and b respectively.

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
