R studio for循环中的错误无法找到解决方案

Question

我在R studio中遇到以下代码的错误。搜索了几天后，我无法找到解决方案。任何帮助表示赞赏！

for(i in 1:nrow(newData)){

#find the week that it corresponds to
  rowsToReplace = newData$date == unique(cleanMovieData$releaseDate[i])

  #find the rank 1 and rank 2 movie in that week
  releaseWeek1 = cleanMovieData$releaseWeekEarnings [which(cleanMovieData$releaseRank[i] == 1)]
  releaseWeek2 = cleanMovieData$releaseWeekEarnings [which(cleanMovieData$releaseRank[i] == 2)]

  #take the log revenue in those weeks and compare
  logReleaseCompare = log(releaseWeek1) - log(releaseWeek2)

  newData$releaseBoxOfficeDiff[rowsToReplace] = logReleaseCompare
}
