如评论中所述,您应该能够执行以下操作(未经测试)将您的列表
展平到一个字符向量中:
As mentioned in the comments, you should be able to do something like this (untested) to get "flatten" your list
into a character vector:
output$Title <- vapply(output$Title, paste, collapse = ", ", character(1L))
也如前所述,如果您想尝试 unlist
方法,则可以通过 output $ Title
,类似这样:
As also mentioned, if you wanted to try the unlist
approach, you could "expand" each row by the individual values in output$Title
, something like this:
x <- vapply(output$Title, length, 1L) ## How many items per list element
output <- output[rep(rownames(output), x), ] ## Expand the data frame
output$Title <- unlist(output$Title, use.names = FALSE) ## Replace with raw values
