Statistical Distributions
- Introduction
- Two namespaces
R::andRcpp::return either a scalar or vector. - Benefit of
Rcpp::default parameters are set. - Benefit of
R::change parameters of sample on each loop.

- Add note emphasizing this is Sugar expressions.
- Mathematical (e.g.
+,-, ...) - Logical (e.g.
>,!=, ...)
- Dimensional Information
- 2D: (
.nrow(),.rows()), (.ncol(),.cols()) - 1D: (
.size(),.length()) [note:.length()is mentioned in STL container] - Exception: the
DataFrameshenanigans... e.g. only.nrows()and.length()/.size()give col info
- 2D: (
- Element Access
- Position Access: elements by numerical id
- Categorical Access: elements by name
- Logical Access: boolean method retrieve values. (cannot move from an 5 by 1)
- Subset Views
- Range
- Subset by Row/Col by using
_e.g.A(0, _ ) - Column and Row reference classes
- Iterators
- iterator accessors

References in Matrices
- Matrix References
*Matrix::Row*Matrix::Column*Matrix::Sub
- References vs.
*Vector- References have a pointer to vector in matrix
*Vectoror*Matrixuses a direct copy of row, col, or submat view via aclone().
Main Data Structures
- RObject
- Policy-based design
- List main policies
- Vector
- 1D homogenous array
- Policies
- typedefs
- constructors
- warn about pointer structure
- example creations (include
clone)
- Matrix
- 2D homogeneous class built on vector
- policies
- typedefs
- constructors
- warn about pointer structure
- example creations (include
clone)
- List (even though it's really just a
Vectorin disguise)- 1D heterogenous array
typedefof vector - note different initialization values (not
0, defaults toNULL) - example creations of named/unnamed with shorthand
_["a"]
- 1D heterogenous array
- DataFrame
- 2D heterogenous
typedefofDataFrame_ImplextendsVector - emphasis special creation
- example creations of named with shorthand
_["a"] - note that unnamed
DataFrames throw an error.
- 2D heterogenous

- Note the C++98 restriction of 10 parameters and the lack of said restriction on C++11 due to variadic templating.
