将作为列表的 data.frame 转换为完整但字符的 data.frame

Posted 2023-03-12

【中文标题】将作为列表的 data.frame 转换为完整但字符的 data.frame

【英文标题】：Convert data.frame that is a list to data.frame that is intact but characters

【发布时间】：2020-08-10 07:36:15

【问题描述】：

我有一个 data.frame，它由每个 URL 的行组成，但是当我运行“typeof”时它的格式是一个列表。当我尝试将其绑定到其他字符或数字格式的 data.frames 时，这会产生一些问题。我正在尝试将这个显示每行因子级别列表的 data.frame 转换为标准 data.frame，其中每个 URL 都完整地占据每一行（长度不变）。

我尝试了以下方法：

test 这给我留下了一个只是数字的向量，不再像我开始使用的任何东西

测试

这是其中一部分的输出：

感谢您的帮助！

【问题讨论】：

str 表明它是一个 vector 类 factor。不清楚你期望的输出是什么

我希望输出不再是一个因素，而是继续使用相同的文本

这是带有 as.character(test) 的输出："c(35, 35, 34, 33, 33, 33, 32, 32, 32, 32, 31, 31, 31, 30 , 29, 27, 28, 27, 26, 26, 25, 24, 24, 24, 23, 23, 23, 23, 23, 22, 22, 22, 21, 20, 20, 19, 19, 18, 18 , 18, 17, 17, 17, 16, 16, 16, 15, 15, 15, 14, 14, 13, 13, 13, 12, 12, 11, 10, 9, 8, 7, 7, 6, 6 , 6, 5, 4, 4, 3, 2, 2, 2, 1, 38, 38, 37, 37, 37, 36, 36)"

我无法重现。我从你的输入中得到as.character(test)# [1] "/Archives/edgar/data/0001218981/000117911020004802/0001179110-20-004802-index.htm" [2] "/Archives/edgar/data/0001218981/000117911020004802/0001179110-20-004802-index.htm"...

【参考方案1】：

如果我们需要将列转换为character，只需提取列并使用as.character

test2$web <- as.character(test2$web)

-检查结构

str(test2)
