替换& quot; \& quot;与& quot;/& quot;在r
问题描述：
我正在尝试用R中的"/"或"\\"替换"\".
I'm trying to replace "\" with "/" or "\\" in R.
fp = "C:\users\jordan\Documents\Computer Science\R\miscData.txt"
replace(fp, "\", "\\")
Output:
> fp = "C:\users\jordan\Documents\Computer Science\R\miscData.txt"
Error: '\u' used without hex digits in character string starting ""C:\u"
很显然，"\"是转义字符，不能以这种方式使用.有没有办法避免在R中使用"\"作为转义字符?
Obviously, "\" is an escape character and can't be used this way. Is there a way to avoid the use of "\" as an escape character in R?
答
您可以使用扫描功能.在您的示例中:
You can use the scan function. In your example:
X = scan(what="character",allowEscapes=F, nmax = 1)
"C:\users\jordan\Documents\Computer Science\R\miscData.txt"
结果:
X
