design.cyclic: Cyclic designs

Description

The cyclic design is a incomplete blocks designs, it is generated from a incomplete block initial of the size k, the plan is generated and randomized. The efficient and robust cyclic designs for 6 to 30 treatments, replications

Usage

design.cyclic(trt, k, r, number = 1, rowcol = FALSE, seed = 0, kinds = "Super-Duper")

Arguments

trt

vector treatments

k

block size

r

Replications

number

number of first plot

rowcol

TRUE: row-column design

seed

init seed random

kinds

random method

Value

• trt
  vector, name of the treatments
• k
  Constant, numeric
• number
  Constant, numeric
• seed
  Constant, numeric
• kinds
  character

Details

Number o treatment 6 to 30. (r) Replication 2 to 10. (k) size of block 2 to 10. replication = i*k, "i" is value integer.
