使用 R 从特定列中隔离元素
[英]Isolating elements from a specific column using R
问题描述
I've been experimenting with the TikTok Scraper tool ( https://github.com/drawrowfly/tiktok-scraper/ ) for a little while and, while I'm not a expert, I've been using R for some of the more simples analysis of the scraped data, but I've experiencing issues with the hashtags scraping.
我一直在尝试使用 TikTok Scraper 工具（ https://github.com/drawrowfly/tiktok-scraper/ ）一段时间，虽然我不是专家，但我一直在使用 R 进行一些对抓取的数据进行更简单的分析，但我遇到了主题标签抓取的问题。
Whenever I scrape data from, let's say, an specific hashtag, I receive data in a format that's not very suitable for my work, for instance:每当我从一个特定的主题标签中抓取数据时，我都会以一种不太适合我的工作的格式接收数据，例如：
***[{"id":"1662240138893317","name":"globolixoo","title":"","cover":""},{"id":"56170","name":"mentira","title":"","cover":""}]***
All that interests to me are the terms that come after "name": — that is, 'globolixoo' and 'mentira'.我感兴趣的只是“名称”之后的术语：即“globolixoo”和“mentira”。
Is there any way in which I can isolate these terms and separate them by comma (globolixoo,mentira)?有什么方法可以隔离这些术语并用逗号分隔它们（globolixoo，mentira）？
Reproducible code example:可重现的代码示例：
dput(head(globolixoo, 10)
