Usage

The easiest way to start a new Bookdown project is from within RStudio IDE. Go to File > New Project > New Directory > Book project using bookdown.

This will create a new directory with an example book as template. You can build the HTML version of this example book without doing any modification:

• Go into the Build Pane in the RStudio IDE
• Click on Build Book > bookdown::gitbook

You can also run bookdown::render_book() in the R console.

Code of Conduct

Please note that the bookdown project is released with a Contributor Code of Conduct. By contributing to this project, you agree to abide by its terms.

2.1 Numbers

Two types of built-in number type, integer and float.

2.1.3 Number Operators

In general, when the operation potentially return float, the result is float type. Otherwise it return integer.

Division always return float

Integer Division by integer return inter. Integer division by float return float.

Remainder by integer return integer.
Remainder by float return float

Power return int or float

2.2 String

String is an object class ‘str.’ It is an ordered collection of letters, an array of object type str

2.2.1 Constructor

2.2.1.1 Classical Method

class str(object=')

class str(object=b', encoding='utf-8', errors='strict')

2.2.1.3 Multiline Method

Note that the variable contain n front and end of the string.

2.2.1.4 Immutability

• String is immuatable. Changing its content will result in error

• Changing the variable completley change the reference (for new object)

2.2.2 Class Constants

2.2.3 Instance Methods

2.2.3.1 Substitution : format()

By Positional

By Name

By Dictionary Name

Formatting Number

Float

Integer, Percentage

Alignment

2.2.3.6 List Related: split()

Splitting delimeter is specified. Observe the empty spaces were conserved in result array

2.2.4 Operator

2.2.4.3in matching

For single string, partial match

For list of strings, exact match (even though only one element in list).
For partial match, workaround is to convert list to single string

2.2.4.4 Comparitor

Comparitor compares the memory address.

2.2.5 Iterations

If step is negative (reverse), end value must be lower than start value

2.3 Boolean

2.3.1 What is Considered False ?

Everything below are false, anything else are true

2.3.2and operator

BEWARE !

• and can return different data types
  
• If evaluated result is True, the last True Value is returned (because python need to evaluate up to the last value)
  
• If evaluated result is False, the first False Value will be returned (because python return it immediately when detecting False value)

2.3.4or operator

• or can return different data type
  
• If evaluated result is True, first True Value will be returned (right hand side value need not be evaluated)
  
• If evaluated result is False, last Fasle Value will be returned (need to evalute all items before concluding False)

2.4 None

2.4.1 None is an Object

• None is a Python object NonType
  
• Any operation to None object will result in error
  
• For array data with None elements, verification is required to check through iteration to determine if the item is not None. It is very computaionaly heavy

2.4.2 Comparing None

2.4.3 Operation on None

Bookdown Python Programming

Any operator (except is) on None results in error.
