我从返回JSON的API导入数据：
substringNotificationData <<- sub('^[^\\{]*\\{', '{', notificationsData)
notificationsDT <<- jsonlite::fromJSON(paste(readLines(textConnection(substringNotificationData),warn="false"), collapse=""))
notificationsbinded <<- do.call(rbind, notificationsDT)
notificationsDataTable<<- notificationsbinded$notifications
这就是我R中的代码。
然而，我一直在：
rownames中的错误（值[[jj]]）[ri]＆lt; - rownames（xij）：
当我正在进行重新绑定时，替换的长度为零。
如何解决此问题？
