nlsList()所属R语言包：nlme
List of nls Objects with a Common Model
免入息审查贷款计划的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 defined in model and individual nls fits are obtained for each data partition, using the model defined in model.
Data根据分组因素水平的model和个人nls一刀切获得每个data分区，使用在模型中定义model定义分区。
用法----------Usage----------
nlsList(model, data, start, control, level, subset, na.action, pool)
## S3 method for class 'nlsList'
update(object, model., ..., evaluate = TRUE)
参数----------Arguments----------
参数：object
an object inheriting from class nlsList, representing a list of fitted nls objects.
一个对象类nlsList代表拟合nls对象名单，继承。
参数：model
either a nonlinear model formula, with the response on the left of a ~ operator and an expression involving parameters, covariates, and a grouping factor separated by the | operator on the right, or a selfStart function. The method function nlsList.selfStart is documented separately.
无论是非线性模型公式，与~运营商和表达涉及参数，变项，|运营商分离的权利和分组因素左侧的响应，或<X >功能。该方法的功能selfStart分开记录。
参数：model.
Changes to the model – see update.formula for details.
该模型的变化 - 看到update.formula详情。
参数：data
a data frame in which to interpret the variables named in model.
在解释model命名的变量的数据框。
参数：start
an optional named list with initial values for the parameters to be estimated in model. It is passed as the start argument to each nls call and is required when the nonlinear function in model does not inherit from class selfStart.
一个可选的命名名单在model要估计的参数的初始值。它作为start参数被传递到每个nls调用，并须model非线性函数时类selfStart不继承。
参数：control
a list of control values passed as the control argument to nls. Defaults to an empty list.
作为control参数nls通过控制值的列表。默认为一个空列表。
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 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：na.action
a function that indicates what should happen when the data contain NAs. The default action (na.fail) causes nlsList 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nlsList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 that is preserved as an attribute of the returned value. This will be used as the default for pool in calculations of standard deviations or standard errors for summaries.
一个可选的逻辑值作为返回值的属性保存。这将作为默认使用pool计算标准偏差或标准错误的总结。
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 nls 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 nlsList object.
nls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nlsList对象。
