这里有两个半复杂的问题。第一个“有人会碰巧知道如何解决移除空白的问题吗？”对于我来说太过模糊和复杂，除了建议使用stringr包中的函数之外真的帮助你？ ¯\ _（ツ）_ /¯idk如果有帮助吗？
第二个“中学：有人可以通过向我展示如何清理我的”referee.report“文本来帮助我吗？这是我最感兴趣的专栏。我特别想删除”\ r \ n n“除其他外。”更多的是要解决的问题。

cleanOutput <- function(listObject){
listObject = sapply(listObject, str_split,"\\r\\n")
listObject = sapply(listObject, trimws)
listObject = paste(listObject[listObject!=""]) ##This line eliminates empty values and NAs
return(listObject)
}
cleanOutput(referee.report)
试试这个功能？
编辑：
此版本从行的开头删除\ t。
编辑： 结果str_trim删除行开头的“\ t”。不需要编辑。

更新所以Polka的代码会运行一些但是lapply删除\，但是因为列表形式的变量我需要将它转换为一个字符但是当我做的时候返回：
更新 paste（）以连接所有字符串并返回单个值会产生相同的结果。
