Just summertime curiosity about strings in R. Let use say that I have a x and y strings. As we know we have to quote single quotes in double quotes and vice versa.
只是夏天对r中弦的好奇假设我有x和y弦。正如我们所知，我们必须引用双引号中的单引号，反之亦然。
x <- "a string with 'single' quotes"
y <- 'another one with "double" quotes'
paste0(x, y)
[1] "a string with 'single' quotesanother one with \"double\" quotes"
cat(x, y)
a string with 'single' quotes another one with "double" quotes
What if we have a string with single and double quotes too? I have tried this: Backticks do not work (R triggers an error):
如果我们有一个单引号和双引号的字符串呢?我尝试过:仰卧起坐不起作用(R触发一个错误):
z <- `a string with 'single' quotes and with "double" quotes`
Use a \" instead of " and then use cat: This works well but the problem is that users must add a backslash to every double quote.
使用一个\“代替”，然后使用cat:这很有效，但是问题是用户必须在每个双引号中添加反斜杠。
z1 <- "a string with 'single' quotes and with \"double\" quotes"
what if we have a huge text file (like a .txt for example) with both type of quotes and we want to read in R?
如果我们有一个很大的文本文件(例如.txt)，包含两种类型的引号，并且我们想要在R中读取，该怎么办?
At this point a (silly) solution to me seems to be: work outside R, do some manipulations (like substitute all " with \") and then read in R. Is this a solution or does exist a better way inside R?
在这一点上，一个(愚蠢的)解决方案似乎是:在R之外工作，做一些操作(比如用“\”替换所有)，然后在R中读取，这是一个解决方案，还是在R中存在更好的方法?
Here is just a little .txt file for example: Link, anyways for who is interested, the file is just a .txt with one line with this text:
这里有一个小的。txt文件，例如:Link，无论如何，对于感兴趣的人来说，这个文件只是一个。txt，只有一行文本:
a string with 'single' quotes and with \"double\" quotes
带有“单”引号和“双\”引号的字符串

You may specify any alternate quoting characters as desired when reading text, e.g.
当你阅读文本时，你可以指定任意的引用字符。
> p<-scan(what="character",quote="`")
1: `It is 'ambiguous' if "this is a new 'string' or "nested" in the 'first'", isn't it?`
2:
Read 1 item
> p
[1] "It is 'ambiguous' if \"this is a new 'string' or \"nested\" in the 'first'\", isn't it?"
Or, just read raw text, e.g. with readline as suggested by @rawr
或者，阅读原始文本，如@rawr建议的readline
> readline()
"It is 'ambiguous' if "this is a new 'string' or "nested" in the 'first'", isn't it?"
[1] "\"It is 'ambiguous' if \"this is a new 'string' or \"nested\" in the 'first'\", isn't it?\""
