Standard Methods
Length, dim, print, format, head and tail methods for vector-like objects.

x |
A suitable object |
.
na.string |
String, what to format NAs as. |
n |
Integer, the number of items. |
value |
A list of character vectors, matching the dimensions of the object. |

Ignored. |
Note that the dimensions of object arrays and nested matrices are the dimensions of the top level object. However, the dimensions of sectioned matrices (including partitioned matrices) are the dimensions of the combined matrix.
You should also use any functions based on dim or dimnames such as nrow or rownames.
The format method for ObjectArray, calls the objtag function, for each of its elements.
The format method for sectioned and partitioned matrices, adds plain-text markup, for separators and section boxes.
Most functions perform the same action as standard R functions.
The format methods return formatted character matrices.
Currently, some of the head, tail functions return formatted character matrices, however, it's possible this may change in the future.
x <- matrix (1:100, 10, 10) pm <- as.PartMatrix (x, 5, c (2, 4, 6, 8) ) nm <- as.NestMatrix (pm) dim (nm) dim (pm) head (nm, 2) head (pm, 2) nm pm
