我有一段时间试图将 JSON 文件转换为数据框。我已经搜索并尝试在我的示例中使用其他人的代码，但似乎没有一个适合。输出始终是列表而不是数据框。

library(jsonlite)
URL <- getURL("http://scores.nbcsports.msnbc.com/ticker/data/gamesMSNBC.js.asp?xml=true&sport=NBA&period=20160104")
URLP <- fromJSON(URL, simplifyDataFrame = TRUE, flatten = FALSE)
URLP

这是答案总是以什么格式结束。

$games
 [1] "<ticker-entry gamecode=\"2016010405\" gametype=\"Regular Season\"><visiting-team display_name=\"Toronto\" alias=\"Tor\" nickname=\"Raptors\" id=\"28\" division=\"ECA\" conference=\"EC\" score=\"\"><score heading=\"\" value=\"0\" team-fouls=\"0\"></score><team-record wins=\"21\" losses=\"14\"></team-record><team-logo link=\"http://hosted.stats.com/nba/logos/nba_50x33/Toronto_Raptors.png\" gz-image=\"http://hosted.stats.com/GZ/images/NBAlogos/TorontoRaptors.png\"></team-logo></visiting-team><home-team display_name=\"Cleveland\" alias=\"Cle\" nickname=\"Cavaliers\" id=\"5\" division=\"ECC\" conference=\"EC\" score=\"\"><score heading=\"\" value=\"0\" team-fouls=\"0\"></score><team-record wins=\"22\" losses=\"9\" ties=\"\"></team-record><team-logo link=\"http://hosted.stats.com/nba/logos/nba_50x33/Cleveland_Cavaliers.png\" gz-image=\"http://hosted.stats.com/GZ/images/NBAlogos/ClevelandCavaliers.png\"></team-logo></home-team><gamestate status=\"Pre-Game\" display_status1=\"7:00 PM\" display_status2=\"\" href=\"http://scores.nbcsports.msnbc.com/nba/preview.asp?g=2016010405\" tv=\"FSOH/SNT\" gametime=\"7:00 PM\" gamedate=\"1/4\" is-dst=\"0\" is-world-dst=\"0\"></gamestate></ticker-entry>"

关于@jbaums 评论，您可以尝试

library(jsonlite) 
library(RCurl)
library(dplyr)
library(XML) 
URL <- getURL("http://scores.nbcsports.msnbc.com/ticker/data/gamesMSNBC.js.asp?xml=true&sport=NBA&period=20160104")
lst <- lapply(fromJSON(URL)$games, function(x) as.data.frame(t(unlist(xmlToList(xmlParse(x)))), stringsAsFactors=FALSE))
df <- bind_rows(lst) 
View(df)

... 理论上。但是，正如@hrbrmstr 指出的那样：实际上，这将违反网站所有者的服务条款。
