R 如何从列表中删除特定字符并另存为数据帧？

我想

获得一个干净的数据集

没有特殊字符

只有用实际的话

没有数字

它来自一个JSON文件

 library(rvest); library(XML); library(dplyr);library(tidyr); library(purrr); library(rjson)

 url <- "http://suggestqueries.google.com/complete/search?client=chrome&q=Nike"
 nike_autocomplete <- read_html(url)

---

因此，最后没有空的东西

您试图提取的文本是JSON格式的，因此您最好使用JSON读取实用程序，而不是尝试使用正则表达式。我喜欢

jsonlite:：fromJSON

library(rvest)
library(jsonlite)
library(purrr)

url <- "http://suggestqueries.google.com/complete/search?client=chrome&q=Nike"
read_html(url) %>%
  xml_text %>%
  fromJSON() %>%
  extract(1:2) %>%
  unlist
#  [1] "Nike"                  "nike shox"             "nike shoes"            "nike air max"         
#  [5] "nike outlet"           "nike air force 1"      "nike basketball shoes" "nike vapormax"        
#  [9] "nike air max 97"       "nike id"               "nike store"            "nike stock"           
# [13] "nike air max 270"      "nike promo code"       "nike windbreaker"      "nike sweatshirts"     
# [17] "nike huarache"         "nike hoodie"           "nike cortez"           "nike sweatpants"      
# [21] "nike slides"

您想要的结果看起来不像数据帧。是一行两列吗？列名是什么？只有一列，重要的是删除第一个空列开头的值。将在第二个列中修改，您确定输入正确吗？当我运行您的

列表时，这是来自JSON文件吗？您可能会更好地改进导入过程，而不是尝试清理导入不好的数据。
