译者:生物统计家园网 机器人LoveR
描述----------Description----------
Function to extract data from corresponding files in the Nimblegen .pair format.
函数来提取相应的文件中的NimbleGen。对格式的数据。
用法----------Usage----------
readPairs(x, y, z, ...)
参数----------Arguments----------
参数:x
the name of the file containing data from signal channel 1. Each line of the file is interpreted as a single data point. If it does not contain an absolute path, the file name is relative to the current working directory, getwd(). Tilde-expansion is performed where supported. Alternatively, x can be a readable connection (which will be opened for reading if necessary, and if so closed at the end of the function call). x can also be a complete URL.
包含从信号通道1的数据文件的名称。文件的每一行被解释为单个数据点。如果它不包含一个绝对路径,文件名是相对于当前的工作目录,getwd()。波浪线扩展进行支持的地方。另外,x可以是一个可读的连接将打开阅读如有必要,如果在函数调用结束时关闭。 x也可以是一个完整的URL。
参数:y
the name of the file containing data from signal channel 1. Each line of the file is interpreted as a single data point. If it does not contain an absolute path, the file name is relative to the current working directory, getwd(). Tilde-expansion is performed where supported. Alternatively, y can be a readable connection (which will be opened for reading if necessary, and if so closed at the end of the function call). y can also be a complete URL.
包含从信号通道1的数据文件的名称。文件的每一行被解释为单个数据点。如果它不包含一个绝对路径,文件名是相对于当前的工作目录,getwd()。波浪线扩展进行支持的地方。另外,y可以是一个可读的连接将打开阅读如有必要,如果在函数调用结束时关闭。 y也可以是一个完整的URL。
参数:z
object in which to store pair information from files. Can be an ExpressionSet, in which case pair data will be stored in featureData.
对象,其中对信息存储文件。可以ExpressionSet,在这种情况下对数据将被储存在featureData。
参数:...
Arguments to be passed to methods (see readPairs-methods):
被传递到方法的参数(见readPairs-methods):
name character input specifying a sample name to assign to the data from specified pair files. If NULL (default), a value will be extracted from the filename specified in x.
name字符输入指定一个样品名称分配给指定对文件的数据。 NULL如果(默认)值将在x指定的文件名中提取。
element.x which element of AssayData (default is "exprs") in which to store signal channel 1 data.
element.x元素AssayData(默认为"exprs"),在其中存储的信号通道1的数据。
element.y which element of AssayData (default is "exprs2") in which to store signal channel 2 data.
element.y元素AssayData(默认为"exprs2"),在其中存储的信号通道2的数据。
match.probes logical specifying whether to match data from pair files by "PROBE\_ID" with any pre-existing data. if TRUE (default), order of values will be rearranged so long as there are already "PROBE\_ID"s specified in featureData.
match.probes逻辑指定是否匹配"PROBE\_ID"任何预先存在的数据对文件的数据。如果TRUE(默认)值的顺序将重新安排,只要已经有"PROBE\_ID"S指定featureData。
path a character vector containing a single full path name to which filenames will be appended. If NULL, filenames (x and y) are treated as is.
path字符向量包含一个单一的完整路径名,文件名将追加。如果NULL,文件名(x和y)作为是治疗。
comment.char character: a character vector of length one containing a single character or an empty string (default is "\#"). Use "" to turn off the interpretation of comments altogether.
comment.char性格特征向量的长度为一包含单个字符或一个空字符串(默认为"\#")。使用""完全关闭评论的解释。
sep the field separator character (default is "\t"). Values on each line of the file are separated by this character. If sep = "" the separator is "white space", that is one or more spaces, tabs, newlines or carriage returns.
sep字段分隔符(默认是"\t")。文件的每一行的值是通过这个角色分离。如果sep = ""分隔符是“白色空间”,这是一个或多个空格,制表符,换行符或回车。
quote the set of quoting characters (default is "\""). To disable quoting altogether, use quote = "". See scan for the behaviour on quotes embedded in quotes. Quoting is only considered for columns read as character, which is all of them unless colClasses is specified.
quote引号字符集(默认是"\"")。完全禁用引用,使用quote = ""。看到scan引号中嵌入引号的行为。只考虑读的性格,这是所有这些,除非colClasses指定的列引用。
eSet ExpressionSet input (default is new("ExpressionSet")) in which to store pair information in assayData
eSetExpressionSet输入(默认为new("ExpressionSet")),其中对信息存储在assayData
verbose logical; if TRUE (default) progress will be output to screen. If FALSE, no output will be displayed.
verbose逻辑;如果TRUE(默认)的进展将是向屏幕输出。如果FALSE,没有输出将显示。
\dots other arguments to be passed to read.table. See read.table.
\dots可以通过read.table其他参数。看到read.table。
值----------Value----------
Returns an ExpressionSet filled with assayData containing matrices of data from both signal channels.
返回ExpressionSet用assayData含矩阵从两个信号通道的数据填充。
and featureData containing the following featureColumns:
和featureData包含以下featureColumns的:
参数:<span class="option">SEQ_ID</span>
a vector of characters with container IDs, linking each probe to a parent identifier
向量的容器ID字符,每个探针连接到父标识符
参数:<span class="option">PROBE_ID</span>
a vector of characters containing unique ID information for each probe
含有独特的ID信息,每个探针的字符向量
and phenoData containing the following sampleColumns:
和phenoData包含以下sampleColumns的:
参数:<span class="option">CHIPS</span>
a vector of characters with .pair file locations for signal channel 1 data
与矢量字符。对信号通道1的数据文件的位置
参数:<span class="option">CHIPS2</span>
a vector of characters with .pair file locations for signal channel 2 data
一个对信号通道2数据文件的位置矢量字符
