qqnorm.lme()所属R语言包：nlme
Normal Plot of Residuals or Random Effects from an lme Object
从LME对象残差或随机效应的正常剧情

描述----------Description----------
Diagnostic plots for assessing the normality of residuals and random effects in the linear mixed-effects fit are obtained. The form argument gives considerable flexibility in the type of plot specification. A conditioning expression (on the right side of a | operator) always implies that different panels are used for each level of the conditioning factor, according to a Trellis display.
诊断图，得到残差和随机效应的线性混合效应合适的常态评估。 form参数，给出了相当的灵活性，在图规范。调理表达（|运营商的右侧）总是意味着不同的面板用于每个调节因子的水平，根据一个网格显示器。
用法----------Usage----------
## S3 method for class 'lme'
qqnorm(y, form, abline, id, idLabels, grid, ...)
参数----------Arguments----------
参数：y
an object inheriting from class lme, representing a fitted linear mixed-effects model or from class lmList, representing a list of lm objects, or from class lm, representing a fitted linear model, or from class nls, representing a nonlinear least squares fitted model.
一个类继承的对象lme，占拟合线性混合效应模型或从类lmList，lm对象名单，或从类lm，较拟合线性模型，或从类nls，代表一个非线性最小二乘拟合模型。
参数：form
an optional one-sided formula specifying the desired type of plot. Any variable present in the original data frame used to obtain y can be referenced. In addition, y itself can be referenced in the formula using the symbol ".". Conditional expressions on the right of a | operator can be used to define separate panels in a Trellis display. The expression on the right hand side of form and to the left of a | operator must evaluate to a residuals vector, or a random effects matrix. Default is ~ resid(., type = "p"), corresponding to a normal plot of the standardized residuals evaluated at the innermost level of nesting.
可选片面的公式，指定所需的类型图。任何用于获取在原来的数据框的变量目前y可以参考。此外，y本身可以使用符号"."公式中引用。可以使用关于|运营商的权利的条件表达式定义在网格显示的独立小组。 form和|操作符左侧右侧的表达式必须评估1残差向量或矩阵随机效应。默认~ resid(., type = "p")，对应到一个正常的最内层嵌套水平评估的标准化残差图。
参数：abline
an optional numeric value, or numeric vector of length two. If given as a single value, a horizontal line will be added to the plot at that coordinate; else, if given as a vector, its values are used as the intercept and slope for a line added to the plot. If missing, no lines are added to the plot.
一个可选的数字值，或长度为二的数字向量。如果作为一个单一的价值，一个水平线将被添加到该坐标的图，否则，如果作为向量，其值添加到图线的截距和斜率。如果缺少，没有行被添加到图。
参数：id
an optional numeric value, or one-sided formula. If given as a value, it is used as a significance level for a two-sided outlier test for the standardized residuals (random effects). Observations with absolute standardized residuals (random effects) greater than the 1 - value/2 quantile of the standard normal distribution are identified in the plot using idLabels. If given as a one-sided formula, its right hand side must evaluate to a logical, integer, or character vector which is used to identify observations in the plot. If missing, no observations are identified.
一个可选的数字值，或片面的公式。如果作为一种价值，它是用来作为显着性水平为两双面离群测试，为标准化残差（随机效应）。绝对的标准化残差（随机效应）比1 - value/2标准正态分布的分位数，更大的意见，确定在使用idLabels图。如果作为一种片面的公式，其右边必须评估逻辑，整数或字符的向量，这是用来确定在图的意见。如果缺少任何意见确定。
参数：idLabels
an optional vector, or one-sided formula. If given as a vector, it is converted to character and used to label the observations identified according to id. If given as a one-sided formula, its right hand side must evaluate to a vector which is converted to character and used to label the identified observations. Default is the innermost grouping factor.
一个可选的向量，或片面的公式。如果作为向量，它被转换为字符，用来标记的意见确定id。如果作为一种片面的公式，它的右边必须评估一个被转换为字符和用来标记鉴定意见的向量。默认是内心的分组因素。
参数：grid
an optional logical value indicating whether a grid should be added to plot. Default is FALSE.
一个可选的逻辑值，该值指示网格是否应该被添加到图。默认FALSE。
参数：...
optional arguments passed to the Trellis plot function.
可选参数传递给格子绘图功能。
值----------Value----------
a diagnostic Trellis plot for assessing normality of residuals or random effects.
格子图评估残差或随机效应的正常诊断。
