描述----------Description----------
Displays a series of plots of the profile t function and interpolated confidence intervals for the parameters in a nonlinear regression model that has been fit with nls and profiled with profile.nls.
显示一系列轮廓t的函数图和插值已适合用nls和profile.nls异形在非线性回归模型参数的置信区间。
用法----------Usage----------
## S3 method for class 'profile.nls'
plot(x, levels, conf = c(99, 95, 90, 80, 50)/100,
absVal = TRUE, ylab = NULL, lty = 2, ...)
参数----------Arguments----------
参数：x
an object of class "profile.nls"
一个对象类"profile.nls"
参数：levels
levels, on the scale of the absolute value of a t statistic, at which to interpolate intervals. Usually conf is used instead of giving levels explicitly.
水平，上规模的绝对值在统计，在插值间隔。通常是conf使用，而不是给levels明确。
参数：conf
a numeric vector of confidence levels for profile-based confidence intervals on the parameters. Defaults to c(0.99, 0.95, 0.90, 0.80, 0.50).
数值向量的参数配置基于置信区间的置信水平。 c(0.99, 0.95, 0.90, 0.80, 0.50).默认
参数：absVal
a logical value indicating whether or not the plots should be on the scale of the absolute value of the profile t. Defaults to TRUE.
一个逻辑值，指明与否图应该是上规模的绝对值资料T。 TRUE默认。
参数：lty
the line type to be used for axis and dropped lines.
线路类型，可用于轴和下降线。
参数：ylab, ...
other arguments to the plot.default function can be passed here (but not xlab, xlim, ylim nor type).
plot.default函数的其他参数可以通过这里（但不xlab，xlim，ylim也type）。
Details
详情----------Details----------
The plots are produced in a set of hard-coded colours, but as these are coded by number their effect can be changed by setting the palette. Colour 1 is used for the axes and 4 for the profile itself. Colours 3 and 6 are used for the axis line at zero and the horizontal/vertical lines dropping to the axes.
图是一套硬编码的颜色，但因为这些都是由数字编码，其效果可以通过设置palette更改。用于轴和4配置文件本身的颜色1。用于在零轴线和水平/垂直线下降到轴的颜色3和6。
