描述----------Description----------
Function to visualize spatial distribution of raw intensities on NimbleGen Oligoarrays. Requires RGList with component genes complete with genes$X and genes$X coordinates of probes on array. arrayImage is a synonym of image.RGList.
功能形象化的NimbleGen Oligoarrays原材料强度的空间分布。需要RGList组件genesgenes$X和genes$X阵列探针的坐标完整。 arrayImage是image.RGList的代名词。
用法----------Usage----------
## S3 method for class 'RGList'
image(x,arrayno,channel=c("red","green","logratio"),
mycols=NULL, mybreaks=NULL, dim1="X", dim2="Y",
ppch=20, pcex=0.3, verbose=TRUE, ...)
参数----------Arguments----------
参数：x
object of class RGList containing red and green channel raw intensities; possibly result of readNimblegen.
可能结果RGList类readNimblegen含有红色和绿色通道的原始强度的对象。
参数：arrayno
integer; which array to plot; one of 1:ncol(x$R)
整数;阵列图;1:ncol(x$R)
参数：channel
character; which channel to plot, either red, green or the logratio log2(red)-log2(green)
字符;渠道图，要么red，green或logratiolog2(red)-log2(green)
参数：mycols
vector of colors to use for image; if NULL defaults to colorRampPalette(c("White", "Yellow", "Red"))(10)
矢量用于图像的颜色;如果NULL默认colorRampPalette(c("White", "Yellow", "Red"))(10)
参数：mybreaks
optional numeric vector of breaks to use as argument breaks in image.default; default NULL means take length(mycols)+1 quantiles of the data as breaks.
可选截断的数字向量作为参数使用breaksimage.default;默认的NULL意味着采取length(mycols)+1作为截断的数据位数。
参数：dim1
string; which column of the 'genes' element of the supplied RGList indicates the first dimension of the reporter position on the microarray surface; for example this column is called 'X' with some NimbleGen arrays and 'Row' with some Agilent arrays.
字符串列基因元素所提供的RGList表明芯片表面上的记者地位的第一个维度，例如这列被称为“X”与一些NimbleGen阵列“和”行“与一些安捷伦阵列。
参数：dim2
string; which column of the 'genes' element of the supplied RGList indicates the second dimension of the reporter position on the microarray surface; for example this column is called 'Y' with some NimbleGen arrays and 'Col' with some Agilent arrays.
字符串列基因元素提供的RGList表明芯片表面上的记者地位的第二个方面，例如这列被称为一些NimbleGen阵列的“Y”和“上校”的一些安捷伦阵列。
参数：ppch
which symbol to use for intensities; passed on as pch to points..default
符号使用强度;通过pchpoints..default
参数：pcex
enlargement factor for intensity symbols; passed on as cex to points.default
cexpoints.default通过强度符号的放大倍数;
参数：verbose
logical; extended output to STDOUT?
逻辑扩展输出到STDOUT？
参数：...
further arguments passed on to plot.default and points.default
通过进一步的论据plot.default和points.default
值----------Value----------
invisibly returns NULL; function is called for its side effect, this is producing the plot
无形返回NULL;函数调用其副作用，这是产生积

举例----------Examples----------
exDir <- system.file("exData",package="Ringo")
exRG <- readNimblegen("example_targets.txt","spottypes.txt",path=exDir)
image(exRG, 1, channel="red", mycols=c("black","darkred","red"))
## this example looks strange because the example data files only[＃这个例子看起来很奇怪，因为例如数据文件只]
## includes the probe intensities of probes mapped to the forward[＃包括正向映射到探测器的探针强度]
## strand of chromosome 9.[＃9号染色体链。]
## you can see these probes are distributed all over the array[＃你可以看到这些探针都分布在阵列]
