Create a new agentMatrix object

This is a fast alternative to the SpatialPointsDataFrame. It is meant to replace that functionality, though there are not as many methods (yet). The object is primarily a numeric matrix. Any character column passed to ... will be converted to a numeric, using as.factor internally, and stored as a numeric. Methods using this class will automatically convert character queries to the correct numeric alternative.

agentMatrix(..., coords)

# S4 method for matrix
agentMatrix(..., coords)

# S4 method for missing
agentMatrix(..., coords)

Arguments

...

Vectors, a data.frame, or a matrix of extra columns to add to the coordinates, or a SpatialPointsDataFrame.

coords

A matrix with 2 columns representing x and y coordinates

Value

An agentMatrix object

Examples

newAgent <- agentMatrix(
  coords = cbind(pxcor = c(1, 2, 5), pycor = c(3, 4, 6)),
  char = letters[c(1, 2, 6)],
  nums2 = c(4.5, 2.6, 2343),
  char2 = LETTERS[c(4, 24, 3)],
  nums = 5:7
)

w1 <- createWorld(
  minPxcor = 0, maxPxcor = 4, minPycor = 0, maxPycor = 4,
  data = runif(25)
)
t1 <- createTurtles(n = 10, coords = randomXYcor(w1, n = 10))
