本文介绍了R语言中用于画图的各种参数设置，包括x（y）axs轴风格、颜色设定、点样式、mfcol/mfrow布局、背景色等。此外，还详细讲解了如par(), col, pch, cex等功能函数的用法，并提到了颜色选择的方法，如heat.colors(), rainbow()等。同时，讨论了如何通过legend()添加图例，以及plot(), density(), lines(), barplot(), hist(), boxplot()等常用绘图函数的应用。" 111778775,10296832,递增复制文字与属性块的LISP程序,"['CAD开发', 'LISP编程', '图形编辑']

par()函数

par can be used to set or query graphical parameters.

x（y）axs

x（y）axs：The style of axis interval calculation to be used for the x（y）-axis. Possible values are "r", "i", "e", "s", "d". The styles are generally controlled by the range of data or x（y）lim, if given.

Style "r" (regular) first extends the data range by 4 percent at each end and then finds an axis with pretty labels that fits within the extended range.

Style "i" (internal) just finds an axis with pretty labels that fits within the original data range.

Style "s" (standard) finds an axis with pretty labels within which the original data range fits.

Style "e" (extended) is like style "s", except that it is also ensures that there is room for plotting symbols within the bounding box.

Style "d" (direct) specifies that the current axis should be used on subsequent plots.

(Only "r" and "i" styles have been implemented in R.)

x（y）asp

A vector of the form c(x1, x2, n) giving the coordinates of the extreme tick marks and the number of intervals between tick-marks when par("x（y）log") is false.
