道歉，如果这个问题有明显的答案，但我还没有找到答案。
所有我正在寻找的错误等同于warnings() - 我想运行一个脚本，然后获取运行脚本时发生的所有错误的列表。
看了traceback()，好像它可能会做我想要的 - 帮助文件说“默认显示是最后一次未捕获错误的堆栈” - 但无法弄清楚如何让它返回所有未被捕获的错误，而不仅仅是最后一个错误。
答案 0 :(得分：1)
我的建议是，保存脚本（例如<div class="Content-inner-pages">
<div class="TopHeading TopHeading2">
<h2>Assets</h2>
@* @Html.ActionLink("Create", "Create")*@
<a class="CreateBtn AssetsBtn" href="Javascript:void(0);" onclick="javascript: HideUpdateButton();">Add Asset</a>
<div class="clearfix"></div>
</div>
<input type="hidden" id="hdnIsNew" value="1" />
<input type="hidden" id="hdnRecId" />
<!-- Slide Popup panel -->
<div class="cd-panel from-right AddAssetForm">
<header class="cd-panel-header">
<h3>Add Asset</h3>
<a href="javascript:void(0);" onclick="javascript: DisplayClear();" class="cd-panel-close">Close</a>
</header>
<div class="cd-panel-container">
<div class="cd-panel-content">

），然后使用script.R运行整个脚本。这将在每个错误时停止。如果您只想查看是否存在错误，这将是一个很好的方法。
