在HTML帮助中设置默认端口号

Question

嗯，标题很明显......是否可以为R的HTML帮助设置默认端口号？每次我启动HTML帮助时，端口号都会改变。

Answer 1

来自help(startDynamicHelp)：

  

详细说明：

 This function starts the internal HTTP server, which runs on the
 loopback interface (‘127.0.0.1’).  If ‘options("help.ports")’ is
 set to a vector of integer values, ‘startDynamicHelp’ will try
 those ports in order; otherwise, it tries up to 10 random ports to
 find one not in use.  It can be disabled by setting the
 environment variable ‘R_DISABLE_HTTPD’ to a non-empty value.

所以看起来您可以尝试通过options("help.ports")覆盖它，并进行适当的设置。随机化似乎是一个特征。
