Reads a HISEA-formatted mixture data file. It attempts to extract lines
containing only numeric data (typical for HISEA mixture files) and
converts them into a numeric matrix.
Usage
read_mixture(filepath = "hisea.mix", nv)
Arguments
- filepath
Character string, the path to the mixture .mix file.
- nv
Integer, the number of variables (columns) expected for each observation
in the mixture data.
Value
A numeric matrix where rows are observations and columns are variables.
Returns an empty matrix (with nv columns) if no valid data is found or errors occur.
