constraints-operators function

Basic operators for constraints objects

Create a subset of a constraints object:

• constraints[i]
• subsetConstraints(constraints, 1:10)

Combine two constraints objects:

• c(constraints1, constraints2)
• combineConstraints(constraints1, constraints2) methods

subsetConstraints(x, i = NULL)

combineConstraints(x1, x2)

## S4 method for signature 'constraints,numeric'
x[i, j, ..., drop = TRUE]

## S4 method for signature 'constraints'
c(x, ...)

Arguments

• x, x1, x2: a constraints object.
• i, j: indices to use in subsetting.
• ...: not used, exists for compatibility.
• drop: not used, exists for compatibility.

Examples

c1 <- constraints_science
c2 <- c1[1:10]
c3 <- c1[c(1, 11:36)] # keep constraint 1 for test length
c4 <- c(c2, c3)
