Selecting hits according to ZScores
选择根据ZScores的命中
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Selects significant genes according to their ZScore.
选择显著基因根据其ZScore。
用法----------Usage----------
hitselectionZscore(dataset, col4zscore, col4sel, thresh, flag, flag2, col4anno,
sumFunc, file4hits)
参数----------Arguments----------
参数:dataset
an R data frame generated with generateDatasetFile
R的数据框生成的以generateDatasetFile
参数:col4zscore
a character vector specifying the name of the column containing the ZScores, usually SigIntensity
字符指定名称的包含的ZScores列的向量,通常是SigIntensity
参数:col4sel
a character vector specifying the name of the new dataset column where hits will be stored
指定一个字符向量命中将存储新的数据集列的名称
参数:thresh
the threshold for the ZScores. The interpretation depends on the choice of the parameter flag2.
阈值为ZScores。的解释取决于参数 flag2的选择。
参数:flag
1 or 2. 1 means the ZScores are kept per well, 2 that they are summarized according to the parameter sumFunc.
1或2。 1表示,他们是根据参数 sumFunc总结的ZScores都保持每口井,2。
参数:flag2
1, 2 or -2. If 1 is chosen and thresh == n, then the n greatest Zscores are chosen as hits. If 1 is chosen and thresh == -n, then the n smallest Zscores are chosen. If 1 is chosen and thresh == 0, all ZScores are chosen and written to the output file. If 2 is chosen, all Zscores greater than or equal to thresh are chosen. If -2 is chosen, all Zscores smaller than or equal to thresh are chosen.
1,2或-2。如果选择 thresh== N,则n的最大Zscores选择为命中。如果选择 thresh==-N,则n的最小Zscores选择。如果选择1和 thresh== 0,所有ZScores是选择,并写入到输出文件。如果选择2,所有Zscores大于或等于 thresh选择。如果选择-2,所有Zscores小于或等于 thresh选择。
参数:col4anno
a character string specifying the name of the dataset column to be used to define the replicate, for example "GeneName" or "Internal_GeneID"
字符串指定被用来定义复制数据集的列的名称,例如, "GeneName"或 "Internal_GeneID"
参数:sumFunc
the function used to summarize ZScore values, e.g. mean or median.
用于总结ZScore值,如功能 mean或 median。
参数:file4hits
the name of the file to store the results in
存储结果的文件名
Details
详情----------Details----------
If flag2 == -2, and there are no ZScores under the defined threshold thresh, the threshold is increased to min(ZScores).
如果 flag2== -2,有下定义的阈值 thresh,阈值提高到 min(ZScores)没有ZScores。
If flag2 == 2, and there are no ZScores over the defined threshold thresh, the threshold is increased to max(ZScores).
,如果 flag2== 2,有超过定义的阈值 thresh没有ZScores,阈值提高到 max(ZScores)。
值----------Value----------
A list containing:
一份列表,列出:
参数:dataset
the dataset with an added column defining the hits in the form of a binary vector
在一个二进制向量形式定义的点击添加的列的数据集
参数:hitVector
the binary vector itself
二进制向量本身
参数:thresh
the threshold for the ZScores
为的ZScores阈值
ZScores are stored in a text output file.
ZScores存储在文本输出文件。
