描述----------Description----------
The IUPAC_CODE_MAP named character vector contains the mapping from the IUPAC nucleotide ambiguity codes to their meaning.
IUPAC_CODE_MAP命名的特征向量包含的IUPAC核苷酸的模糊代码映射到它们的含义。
The mergeIUPACLetters function provides the reverse mapping.
mergeIUPACLetters功能提供反向映射。
用法----------Usage----------
IUPAC_CODE_MAP
mergeIUPACLetters(x)
参数----------Arguments----------
参数:x
A vector of non-empty character strings made of IUPAC letters.
一个非空的字符串向量的IUPAC字母。
Details
详情----------Details----------
IUPAC nucleotide ambiguity codes are used for representing sequences of nucleotides where the exact nucleotides that occur at some given positions are not known with certainty.
IUPAC核苷酸的模糊代码用于较确切发生在一些特定位置的核苷酸不能肯定已知的核苷酸序列。
值----------Value----------
IUPAC_CODE_MAP is a named character vector where the names are the IUPAC nucleotide ambiguity codes and the values are their corresponding meanings. The meaning of each code is described by a string that enumarates the base letters ("A", "C", "G" or "T") associated with the code.
IUPAC_CODE_MAP是一个命名的特征向量的名称的IUPAC核苷酸的模糊代码和价值观是其相应的意义。每个代码的含义是通过的字符串enumarates碱基字母描述("A","C","G"或"T")与代码相关的。
The value returned by mergeIUPACLetters is an unnamed character vector of the same length as its argument x where each element is an IUPAC nucleotide ambiguity code.
mergeIUPACLetters返回的值是一个不愿透露姓名的特征向量作为它的参数的长度相同x,其中每个元素的IUPAC核苷酸的模糊代码。
