法律研究如何在R中分割包含特殊字元的字串值？
當我們擁有一個單一的長字串或一個字串向量，並且字串中的值被一些特殊字元分隔時，分割這些值可以幫助我們更好地理解這些字串。這種情況可能發生在字串資料記錄有錯誤或有其他目的的情況下。我們可以使用`strsplit`函式進行分割。
示例
x1<-"tutorialspoint is an E-learning platform/FREE" x1
輸出
[1] "tutorialspoint is an E-learning platform/FREE"
strsplit(x1,split='/',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform" [2] "FREE"
示例
x2<-"tutorialspoint is an E-learning platform&FREE" x2
輸出
[1] "tutorialspoint is an E-learning platform&FREE"
strsplit(x2,split='&',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform" [2] "FREE"
示例
x3<-"tutorialspoint is an E-learning platform !FREE" x3
輸出
[1] "tutorialspoint is an E-learning platform !FREE"
strsplit(x3,split='!',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform " [2] "FREE"
示例
x4<-"tutorialspoint is an E-learning platform @FREE" x4
輸出
[1] "tutorialspoint is an E-learning platform @FREE"
strsplit(x4,split='@',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform " [2] "FREE"
示例
x5<-"tutorialspoint is an E-learning platform #FREE" x5
輸出
[1] "tutorialspoint is an E-learning platform #FREE"
strsplit(x5,split='#',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform " [2] "FREE"
示例
x6<-"tutorialspoint is an E-learning platform $FREE" x6
輸出
[1] "tutorialspoint is an E-learning platform $FREE"
strsplit(x6,split='$',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform " [2] "FREE"
示例
x7<-"tutorialspoint is an E-learning platform%FREE" x7
輸出
[1] "tutorialspoint is an E-learning platform%FREE"
strsplit(x7,split='%',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform" [2] "FREE"
示例
x8<-"tutorialspoint is an E-learning platform^FREE" x8
輸出
[1] "tutorialspoint is an E-learning platform^FREE"
strsplit(x8,split='^',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform" [2] "FREE"
示例
x9<-"tutorialspoint is an E-learning platform()FREE" x9
輸出
[1] "tutorialspoint is an E-learning platform()FREE"
strsplit(x9,split='()',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform" [2] "FREE"
示例
x10<-"tutorialspoint is an E-learning platform:FREE" x10
輸出
[1] "tutorialspoint is an E-learning platform:FREE"
strsplit(x10,split=':',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform" [2] "FREE"
示例
x11<-"tutorialspoint is an E-learning platform{}FREE"
x11輸出
[1] "tutorialspoint is an E-learning platform{}FREE"strsplit(x11,split='{}',fixed=TRUE) [[1]]
[1] "tutorialspoint is an E-learning platform"
[2] "FREE"示例
x12<-"tutorialspoint is an E-learning platform***FREE" x12
輸出
[1] "tutorialspoint is an E-learning platform***FREE"
strsplit(x12,split='***',fixed=TRUE) [[1]] [1] "tutorialspoint is an E-learning platform" [2] "FREE"
示例
x13<-c("tutorialspoint ^ is", "an ^ E-learning", "platform ^ & FREE")
x13輸出
[1] "tutorialspoint ^ is" "an ^ E-learning" "platform ^ & FREE"
strsplit(x13,split='^',fixed=TRUE) [[1]] [1] "tutorialspoint " " is" [[2]] [1] "an " " E-learning" [[3]] [1] "platform " " & FREE"
示例
x14<-c("tutorialspoint ^is", "an ^E-learning", "platform & ^FREE")
x14輸出
[1] "tutorialspoint ^is" "an ^E-learning" "platform & ^FREE"
strsplit(x14,split='^',fixed=TRUE) [[1]] [1] "tutorialspoint " "is" [[2]] [1] "an " "E-learning" [[3]] [1] "platform & " "FREE"
示例
x15<-c("tutorialspoint^is the best", "resource for^E-learning","in the^world")
x15輸出
[1] "tutorialspoint^is the best" "resource for^E-learning" [3] "in the^world"
strsplit(x15,split='^',fixed=TRUE) [[1]] [1] "tutorialspoint" "is the best" [[2]] [1] "resource for" "E-learning" [[3]] [1] "in the" "world"
