详情----------Details----------
Optionally, R can be built to collate character strings by ICU (http://site.icu-project.org). For such systems, icuSetCollate can be used to tune the way collation is done. On other builds calling this function does nothing, with a warning.
（可选），R可内置整理字符串ICU（http://site.icu-project.org）。对于这样的系统，icuSetCollate可以用来调整的整理完成的方式。其他版本上调用这个函数什么也不做，与警告。
Possible arguments are
可能的参数
locale: A character string such as "da_DK" giving the country whose collation rules are to be used. If present, this
locale："da_DK"给国家，要使用的排序规则，如字符串。如果存在，此
case_first: "upper", "lower" or "default", asking for upper- or lower-case characters to be sorted first. The default is usually lower-case first, but not in
case_first："upper"，"lower"或"default"，大写或小写字符的要求，首先进行排序。默认的通常是小写的第一个，但不是在
alternate_handling: Controls the handling of "variable" characters (mainly punctuation and symbols). Possible values are "non_ignorable" (primary strength) and
alternate_handling：变的字符（主要是标点和符号）控制处理。可能的值是"non_ignorable"（主要力量）和
strength: Which components should be used? Possible values "primary", "secondary", "tertiary"
strength：应使用哪些组件？可能的值"primary"，"secondary"，"tertiary"
french_collation: In a French locale the way accents affect collation is from right to left, whereas in most other locales it is from left to right. Possible values "on", "off"
french_collation：在法语语言环境口音影响整理的方式是由右至左，而在大多数其他语言环境，它是由左到右。可能的值"on"，"off"
normalization: Should strings be normalized? Possible values are "on" and "off" (default). This affects the
normalization：字符串被归？可能的值是"on"和"off"（默认）。这会影响
case_level: An additional level between secondary and tertiary, used to distinguish large and small Japanese Kana

hiragana_quaternary：可能的值"on"（排序
Only the first three are likely to be of interest except to those with a detailed understanding of collation and specialized requirements.
只有前三个都可能有兴趣的整理和专业要求的详细了解除外。
Some examples are case_level="on", strength="primary" to ignore accent differences and alternate_handling="shifted" to ignore space and punctuation characters.
一些例子case_level="on", strength="primary"忽略口音的差异和alternate_handling="shifted"忽略空格和标点字符。
Note that these settings have no effect if collation is set to the C locale, unless locale is specified.
请注意，这些设置整理设置C语言环境，如果没有任何效果，除非locale指定。
注意----------Note----------
As from R 2.9.0, ICU is used by default wherever it is available: this include Mac OS >= 10.4 and many Linux installations.
从R 2.9.0，ICU是默认使用所有可用：这包括Mac OS中> = 10.4和许多Linux安装。
