travis_wait only allows a single command to run for 20 min, but my command is unlikely to finish in 20 min, so let me use a custom version to extend my travis time
quiet devtools::install_github()
use tee to create a file travis_out, the a loop to check if travis_out exists; it it does, remove it, otherwise echo a dot in stdout

this will make sure R's output is not interfered by the while loop here: when R does have stdout output, I will not echo .
quiet apt-get by default
absolutely quiet biocLite
dbmss takes a long time too
these simple packages do not really need a build matrix
the package branch has the prefix pkg/ now
forgot to rename the travis badge
write stderr to stdout
two more recipes
no --amend
