lmList(nlme)
lmList()所属R语言包：nlme
List of lm Objects with a Common Model
LM对象名单的通用模型
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Data is partitioned according to the levels of the grouping factor g and individual lm fits are obtained for each data partition, using the model defined in object.
Data根据分组因素的水平分区g和个人每个lm分区，获得data一刀切使用object定义的模型。
用法----------Usage----------
lmList(object, data, level, subset, na.action, pool)
## S3 method for class 'lmList'
update(object, formula., ..., evaluate = TRUE)
## S3 method for class 'lmList'
print(x, pool, ...)
参数----------Arguments----------
参数：object
For lmList, either a linear formula object of the form y ~ x1+...+xn | g or a groupedData object. In the formula object, y represents the response, x1,...,xn the covariates, and g the grouping factor specifying the partitioning of the data according to which different lm fits should be performed. The grouping factor g may be omitted from the formula, in which case the grouping structure will be obtained from data, which must inherit from class groupedData. The method function lmList.groupedData is documented separately. For the method update.lmList, object is an object inheriting from class lmList.
为lmList，无论是形式的线性公式对象y ~ x1+...+xn | g或groupedData对象。公式中的对象，y代表的响应，x1,...,xn协变量，g分组指定分区的数据，根据不同lm一刀切，应执行的因素。分组因子g可以省略公式，在这种情况下，分组结构将得到data，它必须继承自类groupedData。该方法的功能lmList.groupedData分开记录。该方法update.lmList，object是一个对象，继承类lmList。
参数：formula
(used in update.lmList only) a two-sided linear formula with the common model for the individuals lm fits.
（update.lmList只）双面lm适合个人与通用模型的线性公式。
参数：formula.
Changes to the formula – see update.formula for details.
公式的变化 - 看到update.formula详情。
参数：data
a data frame in which to interpret the variables named in object.
在解释object命名的变量的数据框。
参数：level
an optional integer specifying the level of grouping to be used when multiple nested levels of grouping are present.
一个可选的整数，指定要使用多个嵌套级别的分组分组的水平都存在。
参数：subset
an optional expression indicating which subset of the rows of data 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.
一个可选的表达式的行子集data应在适合使用。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：na.action
a function that indicates what should happen when the data contain NAs. The default action (na.fail) causes lmList 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lmList打印一个错误消息并终止，如果有任何不完整的意见。
参数：pool
an optional logical value indicating whether a pooled estimate of the residual standard error should be used in calculations of standard deviations or standard errors for summaries.
一个可选的逻辑值，该值指示是否应在计算标准差或标准误差为总结汇集的残留标准错误估计。
参数：x
an object inheriting from class lmList to be printed.
一个对象从lmList类继承要打印。
参数：...
some methods for this generic require additional arguments. None are used in this method.
这个通用的一些方法需要额外的参数。没有使用这种方法。
参数：evaluate
If TRUE evaluate the new call else return the call.
如果TRUE评估新的呼叫，否则返回通话。
值----------Value----------
a list of lm objects with as many components as the number of groups defined by the grouping factor. Generic functions such as coef, fixed.effects, lme, pairs, plot, predict, random.effects, summary, and update have methods that can be applied to an lmList object.
lm对象与定义分组因素的群体数量很多的组件列表。通用功能，如coef，fixed.effects，lme，pairs，plot，predict，random.effects，summary ，update有方法可应用于lmList对象。
