Description

Smart Sequyence Generation

Usage

Seq(from, to)

Arguments

from	the startingvalue of the sequence
to	the ending value of the sequence

Details

This function is defined as

  from-1 + seq_len(max(0,to-from+1))

so that when from > to Seq( from, to ) returns numeric(0).

Basically, same as

Seq <- function(from, to) {
  if (from <= to) {
     return(from:to)
  } else {
     return(numeric(0))
  }
}

Examples

for( i in Seq(3,5) ) print(i)
for( i in Seq(5,3) ) print(i)
for( i in seq(5,3) ) print(i)
