Question

我想使用Microsoft R Open通过Microsoft R Server更新R包。我可以在MRAN包repo中看到包版本是1.2.0，但是当我在RStudio中尝试更新时，它说所有包都是最新的，尽管相应的包仍然是1.1.0版（在我的情况下是dbplyr）。为什么R没有更新包？ RStudio指向C:\Program Files\Microsoft\ML Server\R_SERVER。

RStudio IDE具有镜像Global (CDN) - RStudio，但我想这被MRAN否决了？

因此，您运行的是Microsoft R Server，其R版本为3.4.1。我相信当你尝试使用MRAN进行升级时，升级会考虑到你所使用的R版本 - 而且（我相信）dbplyr for R 3.4.1的最新版本是1.1.0。您可以阅读有关快照和检查点的更多信息here。

如果您愿意，可以使用以下代码直接从CRAN仓库安装软件包：

<!doctype html>

<html lang="en">
	<head>
		<title>About Us</title>
		<link href="styles/main.css" rel="stylesheet" type="text/css"/>
		<meta charset="utf-8">

		<link href="about.html" rel="alternate" hreflang="en"/>
		<link href="about_pt.html" rel="alternate" hreflang="pt"/>
	</head>

	<body>
		<div id="imageback" class="fadeImage"></div>

		<header id="aboutus">
			<h1>About Us</h1>
		</header>

		<div class="divcenter">
			<p>

希望这有帮助！
