Drawing Based on R

1. Manage plotting

X11 (): Open a drawing window

? Device: view the list of available drawing devices

Dev. List (): Lists devices.

PDF (): Open a PDF file as a drawing device

Dev. cur (): displays the currently used device

Dev. Set (): change the current device

Dev. Off (): Disable a device.

Win. Metafile (): Open a specific drawing device in Windows

2. Image Segmentation

Split. Screen (): split into multiple parts (with vector parameters)

Screen (): select the image parts

Erase. Screen (): Delete the last drawing.

Layout (): splits the current graph window into multiple parts, and the graph is displayed in each part at a time. Its primary independent variable is an integer matrix, and the element indicates the number of the subwindow.

Layout. Show (): displays the number of subwindows.

3. Drawing Functions

Plot (x): plot with the element value of X as the ordinate and serial number as the abscissa

Plot (x, y): binary plot of X and Y

Sunflowerplot (x, y): Same as above

Pie (x): Pie Chart

Boxplot (x): box chart

Stripchart (x): draws the value of X on a line segment. A smaller sample size can be used as an alternative to a box chart.

Coplot (x ~ Y | z): Draw a binary graph between x and y for each value (or value range) of Z.

Interaction. plot (F1, F2, Y): If F1 and F2 are factors, the mean graph of Y uses different F1 values as the X axis, while F2 values correspond to different curves, other statistics of Y may be specified through fun.

Matplot (x, y): A Binary Graph. The first column of X corresponds to the first column of Y, and the second column of X corresponds to the second column of Y.

Dotchart (x): If X is a data frame, it is used as a Cleveland dot chart (column-by-column enumeration chart)

Fourfoldplot (x): displays 2x2 join tables with four 1/4 circles (X must be an array or matrix of dim = C (2, 2, K)

Assocplot (x): Cohen-friendly diagram, showing the degree of deviation between the row and column variables in a two-dimensional join table from independence

Mosaicplot (x): mosaic of the logarithm Linear Regression residual of the join table

Pairs (x): If X is a matrix or data frame, it is used as a binary graph between columns of X.

Plot. Ts (x): If X is an object of the "ts" type, X can be a time series curve of X, but the sequence must have the same frequency and time.

TS. Plot (x): Same as above, but if X is multivariate, the sequence can have different times but must have the same frequency.

Hist (x): frequency histogram of X

Barplot (x): bar chart of the value of X

Qqnorm (x): normal quantile-quantile chart

Qqplot (x, y): quantile of Y to X-quantile chart

Contour (x, y, z): Contour Map. x and y must be vectors and Z must be matrices, so that dim (z) = C (length (x, z, length (y ))

Filled. contour (x, y, z): Same as above. The area between contour lines is colored.

Image (x, y, z): Same as above, but the actual data size is represented in different colors

Persp (x, y, z): Same as above, but is a perspective

Starts (x): If it is a matrix or data frame, draw it with a star or line segment

Symbols (X, Y,...): draws a symbol at the given coordinates of X and Y. The type, size, and color of the symbol are specified by other variables.

Termplot (mod. OBJ): (partial) Influence Diagram of the regression model (mod. OBJ)

4. Low-Level Drawing command

Points (x, y): Add a vertex

Lines (x, y): add a line

Text (X, Y, labels,...): Add labes text to (x, y)

Mtext (text, side = 3, line = 0 ,...)

Segments (x0, y0, X1, Y1): draw a line segment from each point (x0, y0) to (x1, Y1)

Arrows (x0, y0, X1, Y1, angle = 30, code = 2): Same as above, but add an arrow. If code = 1, 2, 3, draw an arrow at which end

Abline (A, B): draw a straight line with the slope of B and the intercept of

Abline (H = y): Draw a horizontal line at y

Abline (V = X): Draw a vertical line at x

Abline (LM. OBJ): draws a regression line determined by LM. obj.

Rect (x1, x2, Y1, Y2)

Polygon (x, y): Draw a polygon that connects the points of X and Y coordinates.

Legend (X, Y, lengend): Add a legend at (x, y), indicating that the content is given by lengend.

Title (): Add a title or subtitle

Axis (side, vect): draws the coordinate axis

Box (): Add a border to the current Graph

Rug (x): Draw the position of X Data with a short line on the X axis

Locator (n, type = "N ",...): After you click n times on the graph with the mouse, the coordinates (x, y) of N clicks are returned. You can also draw a symbol (type = "p") at the click) or line (type = "1"). No symbols or lines are drawn by default.

Text (X, Y, expression (...): You can draw mathematical formulas.

As. expression (substitute (): You can enter a value in the formula.

5. drawing parameters

PAR (): permanently changing drawing parameters

Xlab, ylab: Axis label

Xlim, ylim: coordinate axis range

PCH, Col, BG: vertex shape, contour color, and background color

Lty: Connection Type

LAS: coordinate axis scale numeric Orientation

Cex, cex. axis, cex. Lab, cex. Main, cex. Sub: controls the size of symbols and text in the default state.
