Hi! I was trying not to install "metacoder" package by bio manager', 'install.packages', 'devtools' and even source '.tar.gz files. But failed to do so. Because it reverses some errors. Please see the attachment.
The error message is telling you the solution, you are missing a system dependency (fontconfig) how to install it depends on which operating system you are using.
Also, please do not post pictures here, they are not very useful, post formatted code instead, here is how to do it
