vecseq: Vectorized Sequences

Description

vecseq returns concatenated multiple sequences

Usage

vecseq(x, y=NULL, concat=TRUE, eval=TRUE)

Arguments

x

vector of sequence start points

y

vector of sequence end points (if is.null(y) then x are taken as endpoints, all starting at 1)

concat

vector of sequence end points (if is.null(y) then x are taken as endpoints, all starting at 1)

eval

vector of sequence end points (if is.null(y) then x are taken as endpoints, all starting at 1)

Value

if concat==FALSE and eval==FALSE a list with n calls that generate sequences if concat==FALSE and eval==TRUE a list with n sequences if concat==TRUE and eval==FALSE a single call generating the concatenated sequences if concat==TRUE and eval==TRUE an integer vector of concatentated sequences

Details

This is a generalization of sequence in that you can choose sequence starts other than 1 and also have options to no concat and/or return a call instead of the evaluated sequence.

Examples

# NOT RUN {
  sequence(c(3,4))
  vecseq(c(3,4))
  vecseq(c(1,11), c(5, 15))
  vecseq(c(1,11), c(5, 15), concat=FALSE, eval=FALSE)
  vecseq(c(1,11), c(5, 15), concat=FALSE, eval=TRUE)
  vecseq(c(1,11), c(5, 15), concat=TRUE, eval=FALSE)
  vecseq(c(1,11), c(5, 15), concat=TRUE, eval=TRUE)
