描述----------Description----------
Function to compute auto-correlation of probe intensities at specified offsets from the original positions.
函数来计算从原来的位置指定的偏移探针强度自相关。
用法----------Usage----------
autocor(x, probeAnno, chrom, samples = NULL, lag.max = 2000,
lag.step = 100, cor.method = "pearson",
channel = c("red","green","logratio"),
idColumn = "ID", verbose = TRUE)
参数----------Arguments----------
参数：x
an object either of class ExpressionSet containing the normalized probe intensities or of class RGList containing the raw intensities.
任何类对象ExpressionSet归探针强度或类RGList包含原始强度。
参数：probeAnno
Object of class probeAnno holding chromosomal match positions and indices of reporters in data matrix.
对象的类probeAnno控股染色体匹配的立场和记者的指数，在数据矩阵。
参数：chrom
character; chromosome to compute the autocorrelation for
字符;染色体计算自相关
参数：samples
which samples of the data to use; if more than 1 for each probe the mean intensity over these samples is taken.
其中使用的数据样本，如果超过1每个探针对这些样品的平均强度。
参数：lag.max
integer; maximal offset from the original position, the auto-correlation is to be computed for.
整数，最大偏移量从原来的位置，自相关计算。
参数：lag.step
integer; step size of lags between 0 and maximal lag.
整数;步大小介于0和最大滞后的滞后。
参数：cor.method
character; which type of correlation to compute, translates to argument method of function cor
字符;哪种类型的相关性来计算，转换method功能参数cor
参数：channel
character; in case x is an RGList, which channel to plot, either red, green or the logratio log2(red)-log2(green)
字符的情况下x是RGList，其中通道绘图，要么red，green或logratiolog2(red)-log2(green)
参数：idColumn
string; indicating which column of the genes data.frame of the RGList holds the identifier for reporters on the microarray. Character entries of the index elements of the probeAnno will be matched against these identifiers. If the index elements of the probeAnno are numeric or x is of class ExpressionSet, this argument will be ignored.
字符串;genes数据框列RGList举行了记者的芯片上的标识。将针对这些标识符匹配的indexprobeAnno元素的字符条目。如果indexprobeAnno元素是数字或x类ExpressionSet，此参数将被忽略。
参数：verbose
logical; extended output to STDOUT
逻辑扩展输出到STDOUT
Details
详情----------Details----------
the lags, i.e. the offsets from the original position, the auto-correlation is to be computed for, are constructed from the given arguments as seq(0, lag.max, by=lag.step).
的滞后，即从原来的位置的偏移量，汽车相关的计算，从seq(0, lag.max, by=lag.step)给定的参数构造。
值----------Value----------
Object of class autocor.result, a numeric vector of auto-correlation values at the offsets specified in argument lags. The lag values are stored as the names of the vector. Argument chrom is stored as attribute chromosome of the result.
对象类autocor.result，数字矢量的自相关值指定的偏移量参数lags。 names向量的滞后值存储。参数chrom属性chromosome结果存储。
