Question

我试图更新我的R版本（3.4.3，有点旧），但是当我尝试安装“安装程序”软件包并加载它时，却出现了错误

> install.packages("installr")
trying URL 
'https://cran.rstudio.com/bin/windows/contrib/3.4/installr_0.20.0.zip'
Content type 'application/zip' length 265893 bytes (259 KB)

package ‘installr’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\abc001\AppData\Local\Temp\RtmpKUhjgr\downloaded_packages

> require(installr)
 Loading required package: installr
Loading required package: stringr
Error: package or namespace load failed for ‘stringr’ in library.dynam(lib, 
package, package.lib):
DLL ‘stringi’ not found: maybe not installed for this architecture?
Failed with error:  ‘package ‘stringr’ could not be loaded’
In addition: Warning messages:
1: package ‘installr’ was built under R version 3.4.4 
2: package ‘stringr’ was built under R version 3.4.4

阅读错误后，我想我当前的问题是'installr'需要'stringr'，但它们基于3.4.4构建。那么，如果“安装程序”依赖于新的R版本（至少3.4.4）但我的当前版本是（3.4.3），那么现在如何更新我的R版本？

谢谢！

尝试安装stringi库。

install.packages("stringi")

然后重试安装程序。

require(installr)

如果安装程序不起作用，如何更新R版本？
