Struct ExprMatrix 

pub struct ExprMatrix { /* private fields */ }

An expression matrix with named rows (features/genes) and columns (samples).

Element (row i, col j) is stored at data[i * ncol + j]. Missing values are represented as f64::NAN (the analog of R’s NA).

Implementations

impl ExprMatrix

pub fn new( row_names: Vec<String>, col_names: Vec<String>, data: Vec<f64>, ) -> ExprMatrix

Build a matrix from row names, column names, and row-major data.

Panics if data.len() != row_names.len() * col_names.len().

pub fn nrow(&self) -> usize

Number of rows (features).

pub fn ncol(&self) -> usize

Number of columns (samples).

pub fn row_names(&self) -> &[String]

Row (feature) names.

pub fn col_names(&self) -> &[String]

Column (sample) names.

pub fn row_of(&self, name: &str) -> Option<usize>

First row index for a feature name, if present.

pub fn get(&self, row: usize, col: usize) -> f64

Value at (row, col).

pub fn row(&self, row: usize) -> &[f64]

A whole row (feature) as a contiguous slice across all samples.

pub fn column(&self, col: usize) -> Vec<f64>

Collect a whole column (sample) as a freshly allocated vector.

Trait Implementations

impl Clone for ExprMatrix

fn clone(&self) -> ExprMatrix

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExprMatrix

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
