makeSliceMap: Make the maps for converting slice notation

In matconv: A Code Converter from the Matlab/Octave Language to R

Description

Make the maps for converting slice notation

Usage

makeSliceMap(leftSym, rightSym, rClass, matClass = "")

Arguments

leftSym	The left symbol that contains the Matlab data
rightSym	the right symbol that contains the Matlab data
rClass	The formal r class name that defines what the R data is outputted as
matClass	The name of the Matlab class that should be converted

Details

Slice notation for matrices are tricky because they can easily be confused with the requirements for conversion are the bounds given by both left and right symbols or the Matlab class. The Matlab class allows for the conversion of structures but is really just a dictionary for the different bounds.

Value

A function that takes in a string and converts all the given slice notation

Examples

  sliceMap <- makeSliceMap("{", "}", "list")
  sliceMap("junk <- importData{300}")
  # "junk <- importData[[300]]"
  
  sliceMap <- makeSliceMap(matClass = "structure", rClass = "list")
  sliceMap("junk <- students.AP.GPA")
  # junk <- students[['AP']][['GPA']]
