This function creates a "byname" matrix, or list of matrices, from .dat
,
depending on the input arguments.
This function is similar to matrix()
, but with "byname" characteristics.
Usage
create_matrix_byname(
.dat,
nrow,
ncol,
byrow = FALSE,
dimnames,
matrix_class = c("matrix", "Matrix")
)
Arguments
- .dat
The data to be used to create the matrix, in a list format, or as a data frame column containing a list of the data to be used for each observation.
- nrow
The number of rows to be used to create the matrix, in a list format, or as a data frame column containing a list of the number of rows to be used for each observation.
- ncol
The number of columns to be used to create the matrix, in a list format, or as a data frame column containing a list of the number of columns to be used for each observation.
- byrow
The argument stating whether the matrix should be filled by rows or by columns (FALSE by column, TRUE by row), in a list format, or as a data frame column containing a list of the byrow argument for each observation. Default is
FALSE.
- dimnames
The dimension names to be used for creating the matrices, in a list format, or as a data frame column containing a list of the dimension names to be used for each observation.
- matrix_class
One of "matrix" or "Matrix". "matrix" creates a
base::matrix
object with thematrix()
function. "Matrix" creates aMatrix::Matrix
object using thematsbyname::Matrix()
function. This could be a sparse matrix. Default is "matrix".
Details
Row and column names are taken from the dimnames
argument.
Any row or column type information on .dat
is preserved on output.
The created object(s) can be of type base::matrix
or Matrix::Matrix
,
the latter enables sparse objects to save both memory and disk.
