Question

我正在尝试从我之前使用MTurkR R包发布的一批HIT中检索结果，并将其写入csv文件。我亲自在MTurkR沙箱中完成了几个，但是当我使用GetAssignments函数时会出现此错误：

a <- GetAssignments(hit.type = git_hit_type$HITTypeId, return.all = T)
Error in `[<-.data.frame`(`*tmp*`, "HITTypeId", value = "3FQBE1TSBOOM7YJ582RRD7RMUYDB6K") : replacement has 1 row, data has 0

我不确定这是否是由HTML文件提交HITS的方式引起的，或者我是否只是使用了错误的函数。任何帮助将不胜感激！

编辑：这是我的HTML代码，可能是问题的一部分：

    </fieldset>
   <p><input type='submit' id='submitButton' value='Submit' /></p>
  </form>
  <script language='Javascript'>turkSetAssignmentID();</script>
 </body>

所以我的问题是，GetAssignments函数可能导致此错误（可能是我的html代码吗？），我该怎么做才能解决这个问题？谢谢！
