Details

These are methods for cbind and rbind for hyperframes.

Note that all the arguments must be hyperframes (because of the peculiar dispatch rules of cbind and rbind).

To combine a hyperframe with a data frame, one should either convert the data frame to a hyperframe using as.hyperframe, or explicitly invoke the function cbind.hyperframe or rbind.hyperframe.

In other words: if h is a hyperframe and d is a data frame, the result of cbind(h,d) will be the same as cbind(as.data.frame(h), d), so that all hypercolumns of h will be deleted (and a warning will be issued). To combine h with d so that all columns of h are retained, type either cbind(h, as.hyperframe(d)) or cbind.hyperframe(h,d).

Examples

if(require(spatstat.random)) {
  lambda <- runif(5, min=10, max=30)
  X <- solapply(as.list(lambda), rpoispp)
  h <- hyperframe(lambda=lambda, X=X)
  g <- hyperframe(id=letters[1:5], Y=rev(X))
  gh <- cbind(h, g)
  hh <- rbind(h[1:2, ], h[3:5,])
}
