Dimensions of an Object

Retrieve or set the dimension of an spam object.

# dim(x)
# dim(x) <- value
<!-- %"dim&lt;-.spam"(x,value) -->

Arguments

x

a spam matrix

value

A numeric two-vector, which is coerced to integer (by truncation).

Value

The replacemnt method changes the dimension of the object by rearranging.

Details

In older version of spam, the behavior of the replacement method was different and is now implemented in pad.spam.

Examples

x <- diag(4)
dim(x)<-c(2,8)
x
#>      [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
#> [1,]    1    0    0    0    0    1    0    0
#> [2,]    0    0    1    0    0    0    0    1

s <- diag.spam(4)
dim(s) <- c(2,8)  # result is different than x

s <- diag.spam(4)
pad(s) <- c(7,3)  # any positive value can be used
