In R , a question about dplyr::bind_rows combine dataframes

问题

有R中的数据框,名称类似于data_1 data_2 data_3 data_4 ....,下面的代码尝试将它们组合在一起,但失败了。如何修复它?谢谢!

dplyr::bind_rows(ls(pattern = "data*"))
英文:

dplyr::bind_rows(ls(pattern = "data*"))

得分: 1

你可以尝试这样做:

dplyr::bind_rows(mget(ls(pattern = "data*"))                       

或者

data.table::rbindlist(mget(ls(pattern = "data*")))

我们只从ls(pattern = "data*")中获取字符串,并需要使用mget将这些字符串转换为对象。

英文:

You may want to try this:

dplyr::bind_rows(mget(ls(pattern = "data*")))                      

or

data.table::rbindlist(mget(ls(pattern = "data*")))

We only get strings from ls(pattern = "data*"), and need to convert those strings to objects using mget.
