如果安装程序不起作用，如何更新R版本？

Question

I was trying to update my R version (3.4.3, a little old) but when i was trying to install 'installr' packages and load it, I got errors

> 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)
downloaded 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 

After reading the errors, i guess my current problem is that 'installr' needs 'stringr' but they are built on 3.4.4. So now how do I update my R version if 'installr' depends on new R version (at least 3.4.4) but my current version is (3.4.3)?

Thank you!

Try installing the stringi library.

install.packages("stringi")

Then re-try installr.

require(installr)
