译者：生物统计家园网 机器人LoveR
描述----------Description----------
If the random effects names defined in random are a subset of the lmList object coefficient names, initial estimates for the covariance matrix of the random effects are obtained (overwriting any values given in random). formula(fixed) and the data argument in the calling sequence used to obtain fixed are passed as the fixed and data arguments to lme.formula, together with any other additional arguments in the function call. See the documentation on lme.formula for a description of that function.
如果随机效果的名称randomlmList对象系数名称的一个子集的定义，协方差矩阵的随机效应的初步估计得到（覆盖random给定的任何值） 。 formula(fixed)和data参数用于获取fixedfixed和data参数lme.formula，连同通过调用序列任何其他额外的参数在函数调用。功能的描述文件lme.formula。
用法----------Usage----------
## S3 method for class 'lmList'
lme(fixed, data, random, correlation, weights, subset, method,
na.action, control, contrasts, keep.data)
参数----------Arguments----------
参数：fixed
an object inheriting from class lmList, representing a list of lm fits with a common model.
对象类继承lmList，代表名单lm适合一个共同的模式。
参数：data
this argument is included for consistency with the generic function. It is ignored in this method function.
这种说法是包括通用功能的一致性。在此方法的功能被忽略。
参数：random
an optional one-sided linear formula with no conditioning expression, or a pdMat object with a formula attribute. Multiple levels of grouping are not allowed with this method function. Defaults to a formula consisting of the right hand side of formula(fixed).
一个可选的双面线性公式，没有空调的表达，或pdMat与formula属性的对象。多层次的分组不允许用这种方法的功能。默认为公式右侧formula(fixed)组成。
参数：correlation
an optional corStruct object describing the within-group correlation structure. See the documentation of corClasses for a description of the available corStruct classes. Defaults to NULL, corresponding to no within-group correlations.
一个可选的corStruct对象，它描述的组内相关结构。可用corClasses类的描述，请参阅文件corStruct。 NULL默认值，相应的组内没有相关。
参数：weights
an optional varFunc object or one-sided formula describing the within-group heteroscedasticity structure. If given as a formula, it is used as the argument to varFixed, corresponding to fixed variance weights. See the documentation on varClasses for a description of the available varFunc classes. Defaults to NULL, corresponding to homoscedastic within-group errors.
一个可选的varFunc对象或片面的公式描述组内异方差结构。如果给出一个公式，它是用来作为的varFixed，相应的固定方差权重的参数。可用varClasses类的描述，请参阅文件varFunc。默认NULL，对应于同方差组内的错误。
参数：subset
an optional expression indicating the subset of the rows of data that should be used in the fit. This can be a logical vector, or a numeric vector indicating which observation numbers are to be included, or a character vector of the row names to be included. All observations are included by default.
一个可选的表达式表示data，应适合使用的行的子集。这可以是一个逻辑向量，或一个数字的向量，被列入观察数字或字符向量的行名被列入。所有的意见，包括默认情况下。
参数：method
a character string. If "REML" the model is fit by maximizing the restricted log-likelihood. If "ML" the log-likelihood is maximized. Defaults to "REML".
一个字符串。如果"REML"模型适合最大限度地限制日志的可能性。如果"ML"日志的可能性最大化。 "REML"默认。
参数：na.action
a function that indicates what should happen when the data contain NAs. The default action (na.fail) causes lme to print an error message and terminate if there are any incomplete observations.
一个函数，它表示数据时，包含NA的，应该发生什么。默认动作（na.fail）导致lme打印一个错误消息并终止，如果有任何不完整的意见。
参数：control
a list of control values for the estimation algorithm to replace the default values returned by the function lmeControl. Defaults to an empty list.
估计算法的控制值的列表来替换默认的返回值的函数lmeControl。默认为一个空列表。
参数：contrasts
an optional list. See the contrasts.arg of model.matrix.default.
可选列表。参见contrasts.argmodel.matrix.default。
参数：keep.data
logical: should the data argument (if supplied and a data frame) be saved as part of the model object?
逻辑：data参数（如果提供的数据框）作为模型对象的一部分保存？
值----------Value----------
an object of class lme representing the linear mixed-effects model fit. Generic functions such as print, plot and summary have methods to show the results of the fit. See lmeObject for the components of the fit. The functions resid, coef, fitted, fixed.effects, and random.effects can be used to extract some of its components.
一个类的对象lme代表线性混合效应模型拟合。通用功能，如print，plot和summary方法来显示合适的结果。看到lmeObject适合的组成部分。职能resid，coef，fitted，fixed.effects，random.effects可以用来提取其组成部分。
