Construct class limits vectors

1	setbreaks(nclass, maxSize, base = NULL, kap = 1, sizeType = c("linear", "exp"))

`nclass`	number of classes
`maxSize`	maximum of `size` values
`base`	constant for size class construction
`kap`	constant for shape class construction
`sizeType`	either `linear` or `exp`, default is `linear`

The function constructs the class limits for the size, shape and orientation parameters. One can either define "linear" class limits of the sizes as a_i=iδ, δ=maxSize/M or using exponentially increasing limits like base^i, i=1,…,M. The orientation classes are defined by θ_j=jω, ω=π/(2N), j=1,…,N in the range [0,π/2], where M,N are the number of size classes and, respectively, the number of orientation classes. The argument base must not be NULL if sizeType equals "exp".
