描述----------Description----------
The DNase data frame has 176 rows and 3 columns of data obtained during development of an ELISA assay for the recombinant protein DNase in rat serum.
DNase数据框有176行,3列的数据,在大鼠血清酶联免疫吸附试验发展的过程中获得了重组蛋白的DNA酶。
用法----------Usage----------
格式----------Format----------
This object of class c("nfnGroupedData", "nfGroupedData", "groupedData", "data.frame") containing the following columns:
本类c("nfnGroupedData", "nfGroupedData", "groupedData", "data.frame")包含下列对象:
an ordered factor with levels 10 < ... < 3 indicating the assay run.
同级别的有序因子10<... <3表明试验运行。
a numeric vector giving the known concentration of the protein.
数字向量,使已知的蛋白质浓度。
a numeric vector giving the measured optical density (dimensionless) in the assay. Duplicate optical density measurements were obtained.
给予一个数值向量检测,测得的光密度(无量纲)。重复获得光密度测量。

详情----------Details----------
This dataset was originally part of package nlme, and that has methods (including for [, as.data.frame, plot and print) for its grouped-data classes.
此数据集原是包nlme部分,并具有分组数据类的方法(包括[,as.data.frame,plot和print) 。

举例----------Examples----------
require(stats); require(graphics)
coplot(density ~ conc | Run, data = DNase,
show.given = FALSE, type = "b")
coplot(density ~ log(conc) | Run, data = DNase,
show.given = FALSE, type = "b")
## fit a representative run[#适合代表运行]
fm1 <- nls(density ~ SSlogis( log(conc), Asym, xmid, scal ),
data = DNase, subset = Run == 1)
## compare with a four-parameter logistic[#比较四参数后勤]
fm2 <- nls(density ~ SSfpl( log(conc), A, B, xmid, scal ),
data = DNase, subset = Run == 1)
