描述----------Description----------

The AlignedXStringSet and QualityAlignedXStringSet classes are containers for storing an aligned XStringSet.
AlignedXStringSet和QualityAlignedXStringSet类容器储存对齐XStringSet。


Details

详情----------Details----------

Before we define the notion of alignment, we introduce the notion of "filled-with-gaps subsequence". A "filled-with-gaps subsequence" of a string string1 is obtained by inserting 0 or any number of gaps in a subsequence of s1. For example L-A–ND and A–N-D are "filled-with-gaps subsequences" of LAND. An alignment between two strings string1 and string2 results in two strings (align1 and align2) that have the same length and are "filled-with-gaps subsequences" of string1 and string2.
我们定义对齐的概念之前,我们引进“的差距,填补与序列”的概念。一个“隙填充与序列”的字符串string1中获得通过插入0或任何数量的差距在S1的序列。例如L-A-Nd和A-ND折价“的差距,填补与子序列”的土地。两个字符串string1和string2两个字符串(align1和align2),有相同的长度和“填写与差距子序列”string1和string2的结果之间的对齐。

For example, this is an alignment between LAND and LEAVES:
举例来说,这是一个土地和树叶之间的对齐:


存取方法----------Accessor methods----------

In the code snippets below, x is a AlignedXStringSet or QualityAlignedXStringSet object.
在下面的代码片段,x是AlignedXStringSet或QualityAlignedXStringSet对象。

unaligned(x): The original string.
unaligned(x):原始字符串。

aligned(x, degap = FALSE): If degap = FALSE, the "filled-with-gaps subsequence" representing the aligned substring. If degap = TRUE, the "gap-less subsequence" representing the aligned substring.
aligned(x, degap = FALSE):如果degap = FALSE,“充满与空白序列”代表的一致的子串。如果degap = TRUE,“无间隙序列”代表的一致的子串。

start(x): The start of the aligned substring.
start(x):对齐子串的开始。

end(x): The end of the aligned substring.
end(x):对齐的子结束。

width(x): The width of the aligned substring, ignoring gaps.
width(x):对齐子串的宽度,无视差距。

indel(x): The positions, in the form of an IRanges object, of the insertions or deletions (depending on what x represents).
indel(x):职位,在IRanges对象的形式插入或缺失(取决于什么x代表),。

nindel(x): A two-column matrix containing the length and sum of the widths for each of the elements returned by indel.
nindel(x):返回一个两列的矩阵,包含的长度和每个元素的宽度的总和indel。

length(x): The length of the aligned(x).
length(x):的aligned(x)长度。

nchar(x): The nchar of the aligned(x).
nchar(x):aligned(x)NCHAR。

alphabet(x): Equivalent to alphabet(unaligned(x)).
alphabet(x):alphabet(unaligned(x))等效。

as.character(x): Converts aligned(x) to a character vector.
as.character(x):aligned(x)字符向量转换。

toString(x): Equivalent to toString(as.character(x)).
toString(x):toString(as.character(x))等效。


子集的方法----------Subsetting methods----------

x[i]: Returns a new AlignedXStringSet or QualityAlignedXStringSet object made of the selected elements.
x[i]:返回一个新的AlignedXStringSet或QualityAlignedXStringSet对象选定的元素。

rep(x, times): Returns a new AlignedXStringSet or QualityAlignedXStringSet object made of the repeated elements.
rep(x, times):返回一个新的AlignedXStringSet或QualityAlignedXStringSet对象反复元素制成。
