（部分）名称查找对象
译者：生物统计家园网 机器人LoveR
描述----------Description----------
apropos() returns a character vector giving the names of all objects in the search list matching what.
apropos()返回一个特征向量，匹配what在搜索列表的所有对象的名称。
find() is a different user interface to the same task.
find()不同的用户界面是相同的任务。
用法----------Usage----------
apropos(what, where = FALSE, ignore.case = TRUE, mode = "any")
find(what, mode = "any", numeric = FALSE, simple.words = TRUE)
参数----------Arguments----------
参数：what
character string with name of an object, or more generally a regular expression to match against.
对象的名称，或更普遍的正则表达式匹配的字符串。
参数：where, numeric
a logical indicating whether positions in the search list should also be returned
指示是否在搜索列表中的位置也应该返回逻辑
参数：ignore.case
logical indicating if the search should be case-insensitive, TRUE by default. Note that in R versions prior to 2.5.0, the default was implicitly ignore.case = FALSE.
逻辑表示如果搜索是区分大小写的，TRUE默认。请注意，在R版本2.5.0前，默认是隐含ignore.case = FALSE。
参数：mode
character; if not "any", only objects whose mode equals mode are searched.
字符;如果不是"any"的mode等于mode搜索的对象。
参数：simple.words
logical; if TRUE, the what argument is only searched as whole word.
逻辑，如果TRUE，what参数仅作为整个单词搜索。
Details
详情----------Details----------
If mode != "any" only those objects which are of mode mode are considered. If where is TRUE, the positions in the search list are returned as the names attribute.
如果mode != "any"被认为是只有那些对象模式mode。 where如果是TRUE，在搜索列表中的位置返回的名称属性。
find is a different user interface for the same task as apropos. However, by default (simple.words == TRUE), only full words are searched with grep(fixed = TRUE).
find是一个相同的任务apropos不同的用户界面。然而，默认情况下（simple.words == TRUE），只有完整的单词搜索grep(fixed = TRUE)。
值----------Value----------
For apropos character vector, sorted by name, possibly with names giving the (numerical) positions on the search path.
apropos矢量字符，按名称排序，可能给搜索路径上的位置（数值）的名称。
For find, either a character vector of environment names, or for numeric = TRUE, a numerical vector of positions on the search path, with names giving the names of the corresponding environments.
find，无论是环境名称的字符向量，或numeric = TRUE，数值向量的搜索路径上的位置，给予相应的环境的名称的名称。

举例----------Examples----------
require(stats)
## Not run: apropos("lm")[＃无法运行：中肯（“LM”）]
apropos("GLM") # more than a dozen[十多]
## that may include internal objects starting '.__C__' if[＃可能包括启动内部对象。__C__如果]
## methods is attached[＃方法附]
apropos("GLM", ignore.case = FALSE) # not one[没有一个]
apropos("lq")
cor <- 1:pi
find("cor") #> ".GlobalEnv" "package:stats"[“GlobalEnv。”>“包：统计”]
find("cor", numeric=TRUE) # numbers with these names[这些名称的号码]
find("cor", numeric=TRUE, mode="function")# only the second one[只有第二个]
rm(cor)
## Not run: apropos(".", mode="list") # a long list[＃无法运行：中肯（“。”模式“列表”）＃一个长长的列表]
# need a DOUBLE backslash '\\' (in case you don't see it anymore)[需要双反斜线\ \（的情况下，你看不出来了）]
apropos("\\[")
## Not run: # everything [＃不运行：＃一切]
length(apropos("."))
# those starting with 'pr'[那些与“公关”开始]
apropos("^pr")
# the 1-letter things[1字母东西的]
apropos("^.$")
# the 1-2-letter things[1-2-信的东西]
apropos("^..?$")
# the 2-to-4 letter things[2至4信的东西]
apropos("^.{2,4}$")
# the 8-and-more letter things[信8和更多的东西]
