struct2dataframe: Load MATLAB structs as R data frames

In ks905383/importr: Utilities to Ease the Import of Data from Stata, MATLAB, and Others

Description

A simple wrapper for readMat for structs that additionally converts the resulting list into a data frame.

Usage

struct2dataframe(fn, var = c())

Arguments

fn	A full (character) filename path pointing to the desired .mat file created by save(). The file must be saved in v6 or before (since R.matlab can't deal with HDF5-like files yet).
var	A character variable name, if a specific variable is desired from the .mat file. If no variable is specified, struct2datable will attempt to process the first variable listed.

Details

struct2dataframe is basically just a replacement for a few lines of code, but saves some time and ensures that the struct you clearly meant as a data frame for processing or plotting in R actually shows up as a data frame.

Value

A data frame will be returned with the struct fields as variables and the struct elements as observations

Examples

## Not run: struct2dataframe("~/code/some_struct_v6.mat")
