feat2dens()所属R语言包:ChIPsim
Convert a list of features into a feature density
转换成一个功能密度的功能列表
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Given a list of features (as produced by makeFeatures) computes the feature density for each and combines them into a chromosome wide density.
鉴于的功能列表(makeFeatures生产)计算每个功能密度,并把它们结合成一个染色体全密度。
用法----------Usage----------
feat2dens(features, length, featureBgr = TRUE, ...)
参数----------Arguments----------
参数:features
A list of features.
功能列表。
参数:length
Total length of feature density vector (i.e. chromosome length). If this is missing the length is inferred from the feature parameters.
总长度的功能密度矢量(即染色体的长度)。如果这是失踪的长度从功能参数的推断。
参数:featureBgr
Logical indicating whether feature specific background should be added to the density. If this is TRUE the resulting density for each feature is a mixture of the feature density and a fuzzy, i.e. uniform, feature density. The weights of the components are determined by the feature weight.
逻辑显示功能的特定背景是否应增加密度。如果这是TRUE每个功能的密度是一个混合的功能密度和模糊的,即统一的,功能密度。组件的权重确定的特征权重。
参数:...
Further arguments to featureDensity.
featureDensity进一步的论据。
值----------Value----------
A vector with the feature density for each position along the chromosome.
一个向量与染色体沿每个位置的功能密度。

The majority of the work is done by calls to featureDensity and joinRegion.
大多数的工作是做检测featureDensity和joinRegion。
举例----------Examples----------
set.seed(1)
## generate a (relatively short) sequence of nucleosome features[#产生的核小体的功能(比较短)序列。]
features <- placeFeatures(start=200, length=1e5)
## calculate density[#计算密度]
featureDens <- feat2dens(features, length=1e5)
