It means exactly what it says. You don't have write permission in that folder. Either you need to <a href="https://help.ubuntu.com/community/FilePermissions" rel="noreferrer">change the permissions for that folder</a>, or <a href="https://stackoverflow.com/q/2698269/2954547">change the R library location</a>.

blocks|key|4468950|text|如果您将R与RStudio一起使用，而不是使用托盘图标启动RStudio，请使用sudo+rstudio或sudo+R通过命令行启动Rstudio或R。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4468951|它肯定会解决你的问题，它对我很有效。需要sudo权限才能在安装目录中写入内容。|4468952|entityMap^0|14|C|1H|6|0|K|4|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|R|8|@]|D|@]|E|$]]]|I|$]]

If you are using R with RStudio, rather than starting RStudio with tray icon, start Rstudio or R with command line using <code>sudo rstudio</code> or <code>sudo R</code>. 

It will solve your problem for sure, it works for me. It requires <code>sudo</code> privilege to write something in installation directory.

add yourself to the group called 'staff'

<pre><code>sudo usermod -a -G staff your_user_name

replace your_user_name with your login username, then logoff and relogin.

DO NOT use chmod 777 which is a breach of security and btw. a complete non-sense!!!

blocks|key|4469123|text|如果您使用的是Windows，则可以以管理员身份运行R(或RStudio)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4469124|关闭R，然后转到R或RStudio图标，右键单击并“以管理员身份打开”。它工作完美，安装包时的所有错误消息都将永远消失。|4469125|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

If you are on Windows, you can run R (or RStudio) as an administrator.

Close your R, then go to the R or RStudio icon, right-click and "open as administrator". It works perfectly, all error messages while installing packages are gone forever.

If you are using OS windows 10 then maybe Ransomware protection is on. You need to disable that.

I was facing the same problem. I had the access to write. but suddenly it stopped. I couldn't install the packages. Disabling Ransomware protection worked for me.

The <code>&quot;XX&quot; is not writable</code> error can also mean that the library path you're providing does not exist.

I have this issue during package installation in R version 3.0.2 (2013-09-25) on an Ubuntu machine:

<pre><code>install.packages("randomForest")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning in install.packages :
 'lib = "/usr/local/lib/R/site-library"' is not writable

How to resolve it?

Library is not writable

Ubuntu

在Ubuntu机器上安装R版本3.0.2 (2013-09-25)的软件包时，我遇到了这个问题：install.packages("randomForest")Installing package into ‘/usr/local/lib/R/site-library’(as ‘lib’ is unspecified)...
