dimNA< -: Sets the dimension of an object with the option to infer one dimension automatically

Description

Sets the dimension of an object with the option to infer one dimension automatically. If one of the elements in the dimension vector is NA, then its value is inferred from the length of the object and the other elements in the dimension vector. If the inferred dimension is not an integer, an error is thrown.

Usage

dimNA(x) <- value

Arguments

  stopifnot(dim(x) == as.integer(c(2,2,3)))
# }
