Create a diagonal matrix from a character vector
Create a diagonal matrix from a character vector
## S4 method for signature 'character' diag(x = 1, nrow, ncol)
x |
Character vector used to create the matrix |
nrow |
Numeric. Number of rows for the resulting matrix. |
ncol |
Numeric. Number of columns for the resulting matrix. |
We create a new method for diag with character input. The default behavior for missing nrow and/or ncol arguments is the same
as for the diag function in the base package. Off-diagonal entries
are filled with "0".
