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 <= 10.

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

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.

Value

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