# R for travis: see documentation at https://docs.travis-ci.com/user/languages/r

#language: R
#cache: packages
#script: 
#  - travis_wait 120 R -e 'rmarkdown::render("appendix/appendixA.Rmd")'
#  - travis_wait 60 R -e 'rmarkdown::render("appendix/appendixB.Rmd")'
#  - R -e 'rmarkdown::render("manuscripts/manuscript.Rmd")'
  
## Travis lacks enough memory to handle appendices
## test that all .Rmd files can render 
#  - R -e 'lapply(list.files(pattern=".*.Rmd", recursive=TRUE), rmarkdown::render)'
## Optionally check linting  
#  - R -e 'lapply(list.files(pattern=".*.Rmd", recursive=TRUE), function(x) testthat::expect_length(lintr::lint(x),0))'


## Alternate recipe: use Docker instead of R travis
