Question

我需要从数据框中删除所有撇号，但是一旦我使用....

textDataL <- gsub("'","",textDataL)

当我只想从可能存在的任何文本中删除任何撇号时，数据框会被破坏并且新数据框只包含值和NA？我是否遗漏了撇号和数据框明显的东西？

Answer 1

保持结构完整：

 dat1 <- data.frame(Col1= c("a woman's hat", "the boss's wife", "Mrs. Chang's house", "Mr Cool"),
 Col2= c("the class's hours", "Mr. Jones' golf clubs", "the canvas's size", "Texas' weather"),
 stringsAsFactors=F)

我会用

     dat1[] <- lapply(dat1, gsub, pattern="'", replacement="")

或

     library(stringr)
     dat1[] <- lapply(dat1, str_replace_all, "'","")
 dat1
#                Col1                 Col2
# 1      a womans hat     the classs hours
# 2    the bosss wife Mr. Jones golf clubs
# 3 Mrs. Changs house     the canvass size
# 4           Mr Cool        Texas weather

Answer 2

您不希望直接在数据框上应用gsub，而是以列为单位，例如

apply(textDataL, 2, gsub, pattern = "'", replacement = "")

数据框R中的Gsub撇号
