Hi @rgallego!
the Killed keyword there to me implied that your project was potentially running out of memory while compiling the package. I've confirmed that to be the case -- I was able to successfully install this package in a new project using only:
install.packages('devtools')
devtools::install_github("benjjneb/dada2")
after setting my project resources to have 4GB of ram accessible. You may not need 4GB of ram for this to be successful and could try first with 2GB of ram. Please note that at this time, you need a subscription to set the amount of resources required for your project above 1CPU/1GB ram.
