Грамматика графики - подход к визуализации статистических данных, позволяющий перейти к содержательной части графика и не отвлекаться второстепенные детали, которые создаются автоматически. Ggplot2 - расширение Хэдли Викхэма для среды статистической обработки данных R, реализующее концепцию грамматики графики. Для создания графика в ggplot2 пользователь указывает исходный массив данных, сопоствляет переменным из массива подходящие средства графического представления (такими могут быть положение по вертикали и горизонтали, размер, цвет заливки, цвет обводки, форма и др.), выбирает тип геометрического объекта (например, точка, прямоугольник, линия, изолиния, ящик с усами и пр.), и при необходимости устанавливает способ статистического преобразования данных, тип координатной системы.
Ggmap - расширение Дэвида Кахли для R, "заточенное" под создание картограмм и основанное на ggplot2. В качестве положения по вертикали и горизонтали в ggmap зафиксированы широта и долгота, в качестве проекции - Меркатор.

Kieran, as a teenager, fits stereotypes of being eccentric and dangerous. The film represents social groups through its choice of weapon, setting, and protagonists in non-conventional ways compared to expectations. Specifically, it shows the crime from Kieran's home rather than a typical alleyway, and the protagonist is middle-class rather than working-class.

Scatter plots use a series of points to represent a relationship between two variables, with the x-axis representing one variable and the y-axis representing the other. A scatter plot should include a title, labeled x-axis, and labeled y-axis. Correlation can be positive if points increase from left to right, negative if points decrease from left to right, or no correlation if points have no trend. A line of best fit shows the overall trend of the data by having the same number of points above and below the line.

PC 1 continuity notes
A continuous function is defined as one that is defined at a point c, where the limit exists and the function approaches the same y-value from both sides of point c. A function may be discontinuous due to an infinite jump, a jump, or a point discontinuity. Rational functions are defined as the quotient of two polynomial functions. They have asymptotes which occur where the denominator is zero, creating either a vertical or horizontal asymptote in the graph. The end behavior of functions can be determined by considering whether they are increasing or decreasing over different intervals.
PC 1 continuity
This document discusses continuity and discontinuities in functions, defining continuous functions as smooth curves where the domain includes all real numbers. It presents tests for continuity, requiring a function to be defined at a point, have an existing function value, and approach the same y-value from both sides. Critical points and extrema are defined as maximums where a function changes from increasing to decreasing, and minimums where it changes from decreasing to increasing. Rational functions are described as the quotient of two polynomial functions, with limited domains and possible vertical asymptotes.
