BufferedMatrix-class {BufferedMatrix} | R Documentation |
This is a class representation of a buffered matrix (of numeric data). In this case data is primarily stored outide main memory in temporary files.
Objects can be created using the function createBufferedMatrix
rawBufferedMatrix

:
signature(object = "BufferedMatrix")
: Returns the number of columns in the matrixsignature(object = "BufferedMatrix")

vector containing minimums by column
signature(object = "BufferedMatrix")
: Returns a
vector containing minimums by row
signature(object = "BufferedMatrix")
: Returns a
vector containing sample variances by column
signature(object = "BufferedMatrix")
: Returns a
vector containing sample variances by row
signature(object = "BufferedMatrix")
: Returns a
vector containing sample standard deviations by column
signature(object = "BufferedMatrix")
: Returns a
vector containing sample standard deviations by row
signature(object = "BufferedMatrix")
: Returns a
vector containing sum by column
signature(object = "BufferedMatrix")
: Returns a
vector containing sum by row
signature(object = "BufferedMatrix")
: Returns a
vector containing medians by column
signature(object = "BufferedMatrix")
: Returns a
vector containing medians by row. Best only used when the matrix is
in RowMode (otherwise it is extremely slow)
signature(object = "BufferedMatrix")
: Returns the
maximum of all elements in the matrix
signature(object = "BufferedMatrix")
: Returns the
minimum of all elements in the matrix
signature(object = "BufferedMatrix")
