如何将此数据强制放入data.frame？

我试图将这些数据解析成有意义的格式。我无法摆脱\t\n\t\t\t。请帮忙

#Loading the rvest package
library('rvest')

# Define the url once.
URL <- "https://rotogrinders.com/pages/pga-course-history-743469"

tablescrape_html <- read_html(URL)
tablescrape_html

tablescrape_html %>%
html_nodes("table") %>%
head()


tablescrape_html %>%

html_nodes("tr") %>% #grab the <td> tags
html_text() %>% # isolate the text from the html tages
gsub("^\\s+|\\s+$", "", .) %>% #strip the white space from the beginning and  end of a string.
head(n=100) # take a peek at the first 100 records

您需要将向量按\t\n进行拆分。为了使它成为一个数据帧，然后强制所有向量具有相同的长度，并将所有行绑定到一个表中

library(tidyverse)
tablescrape_html %>%
  html_nodes("tr") %>% #grab the <td> tags
  html_text() %>% # isolate the text from the html tages
  gsub("^\\s+|\\s+$", "", .) %>% 
  str_split("\\t\\n\\t+[ \t]*") %>% 
  map(`length<-` ,7) %>% 
  do.call(rbind,.)

将制表符制成的分隔符、行尾和空格替换为单空格，并将标题和填充集传递到read.table：

input <- tablescrape_html %>%

html_nodes("tr") %>% 
html_text() %>% 
gsub("[\t\n ]+", " ", .) %>% 
read.table(text=., fill=TRUE, header=TRUE)
str(input)
> str(input)

您的标题说要将其强制为data.frame，而在描述中，它是要删除\t\n。如果最终输出是data.frame，则不清楚列是什么
