我的数据框中有一列,此列包含以;分隔的文本数据;
x1 =c ("Anal Exam Under ;", "Sigmoidoscopy;Colonoscopy; Esophagogastroduodenoscopy;" ,"Fistula
Repair;Percutaneous Endo. G-Tube (PEG);" ,"Sigmoidoscopy;Anorectal Motility/Anorectal Manometry
(ARMS);","Sigmoidoscopy;Colonoscopy;", "Procedure; Auditory Brain Stem ;", "Colonoscopy; EGD
(Endoscopy Upper GI);", "Eye Exam; Lumbar Puncture; MRI Scan;
EGD (Endoscopy Upper GI);", "EUS Upper GI (Endoscopic Ultrasound); Sigmoidoscopy;")
x1
[1] "Anal Exam Under ;"
[2] "Sigmoidoscopy;Colonoscopy; Esophagogastroduodenoscopy;"
[3] "Fistula Repair;Percutaneous Endo. G-Tube (PEG);"
[4] "Sigmoidoscopy;Anorectal Motility/Anorectal Manometry (ARMS);"
[5] "Sigmoidoscopy;Colonoscopy;"
[6] "Procedure; Auditory Brain Stem ;"
[7] "Colonoscopy; EGD (Endoscopy Upper GI);"
[8] "Eye Exam; Lumbar Puncture; MRI Scan;\nEGD (Endoscopy Upper GI);"
[9] "EUS Upper GI (Endoscopic Ultrasound); Sigmoidoscopy;"
如果遇到文本,我如何将文本换行到该单元格中的新行(不是新行),新行;
例如,第二次和第三次观察是
[2] "Sigmoidoscopy;Colonoscopy; Esophagogastroduodenoscopy;"
[3] "Fistula Repair;Percutaneous Endo. G-Tube (PEG);"
我希望它看起来像
[2] "Sigmoidoscopy;Colonoscopy;
Esophagogastroduodenoscopy;"
[3] "Fistula Repair;
Percutaneous Endo. G-Tube (PEG);"
需要一些帮助。

使用gsub()
将;
的所有实例替换为前导和尾随空格。
试试这个:
z <- gsub(" *; *\n* *", "\n", x1)
cat(z)
结果
Anal Exam Under
Sigmoidoscopy
Colonoscopy
Esophagogastroduodenoscopy
Fistula
Repair
Percutaneous Endo. G-Tube (PEG)
Sigmoidoscopy
Anorectal Motility/Anorectal Manometry
(ARMS)
Sigmoidoscopy
Colonoscopy
Procedure
Auditory Brain Stem
Colonoscopy
EGD
(Endoscopy Upper GI)
Eye Exam
Lumbar Puncture
MRI Scan
EGD (Endoscopy Upper GI)
EUS Upper GI (Endoscopic Ultrasound)
Sigmoidoscopy
