I want to install xtail without Docker

[LucasLiu20200131]

Hi,
Thanks for share and maintain this wonderful package. I found it difficult using xtail becasue I'm not root user and can't use Docker. However, I tried methods in the INSTALL file either using devtools::install_github nor downing the source package and compile along. They did not work for me.
Would you please find out why and update this package?

below is the error message:
System command 'R' failed, exit status: 1, stdout + stderr (last 10 lines):
E> isnan(double __x)
E> ^
E> /usr/include/c++/4.8.2/cmath:618:3: note: constexpr bool std::isnan(float)
E> isnan(float __x)
