Legend Functions for Strucplots
联想功能Strucplots
译者：生物统计家园网 机器人LoveR
描述----------Description----------
These functions generate legend functions for residual-based shadings.
这些功能生成图例的功能，剩余阴影。
用法----------Usage----------
legend_resbased(fontsize = 12,
x = unit(1, "lines"), y = unit(0.1,"npc"),
height = unit(0.8, "npc"),
width = unit(0.7, "lines"),
digits = 3, check_overlap = TRUE, text = NULL,
steps = 200, ticks = 10, pvalue = TRUE, range = NULL)
legend_fixed(fontsize = 12, x = unit(1, "lines"), y = NULL,
height = NULL, width = unit(1.5, "lines"), steps = 200,
digits = 1, space = 0.05, text = NULL, range = NULL)
参数----------Arguments----------
参数：fontsize
fontsize of title and p-value text.
字号的标题和P-值的文本。
参数：x, y
objects of class "unit" indicating the coordinates of the title. For legend_fixed, the default for y is computed as to leave enough space for the specified text.
对象的类"unit"指示坐标的称号。 legend_fixed，默认为y的计算方法为指定的text留下足够的空间。
参数：height, width
object of class "unit" indicating the height/width of the legend. For legend_fixed, the default for y is computed as to align upper margins of legend and actual plot.
类的对象"unit"指示的高度/宽度的传说。对于legend_fixed，默认为y计算对齐上边缘的传说和实际的图。
参数：digits
number of digits for the scale labels.
刻度标签的位数的数目。
参数：check_overlap
logical indicating whether overlap of scale labels should be inhibited or not.
逻辑的刻度标签的重叠是否应被禁止或不。
参数：space
For legend_fixed only: proportion of space between the tiles.
对于legend_fixed只有瓷砖之间的空间比例。
参数：text
character string indicating the title of the legend.
字符串表示的标题的传说。
参数：steps
granularity of the color gradient.
颜色渐变的粒度。
参数：ticks
number of scale ticks.
数量规模刻度线。
参数：pvalue
logical indicating whether the p-value should be visualized under the scale or not.
逻辑指示p-值是否垢下或不应该被可视化。
参数：range
Numeric vector of length 2 for setting the legend range. Computed from the residuals if omitted. NA values are replaced by the corresponding minimum / maximum of the residuals.
数字矢量长度为2的设置的传奇范围。从残差计算，如果省略。由相应的最小/最大残差NA的值所取代。
Details
详细信息----------Details----------
These functions generate legend functions for residual-based shadings, visualizing deviations from expected values of an hypothesized independence model. Therefore, the legend uses a supplied shading function to visualize the color gradient for the residuals range. legend_fixed is inspired by the legend used in mosaicplot. For more details on the shading functions and their return values, see shadings.
这些功能剩余阴影生成图例的功能，可视化的虚拟独立模型的预期值的偏离。因此，Legend采用的是提供的遮光功能，可视化的颜色渐变的残差范围。 legend_fixed的灵感来自的传说在mosaicplot。遮光功能以及它们的返回值的详细信息，请参阅shadings。
值----------Value----------
A function with arguments:
的功能与参数：
参数：residuals
residuals from the fitted independence model to be visualized.
从拟合的独立模型的残差可视化。
参数：shading
shading function computing colors from residuals (see details).
阴影残差（见详情）函数计算的颜色。
参数：autotext
character vector indicating the title to be used when no text argument is specified. Allows strucplot to generate sensible defaults depending on the residuals type.
字符向量表示时要使用没有text参数指定的标题。 ，允许strucplot产生合理的默认值，根据残差类型。
