Installing OSLERinHealth Packages

Install and start the latest release version of R. Although the installer will try to download and install devtools, there may be some system requirements for devtools that you may need before going forward. Please visit installing devtools before going forward if you do not have devtools currently installed.

Then, you can install a package using the following command:

## try http:// if https:// URLs are supported

where PACKAGE is the name of the package you’d like to install, such as baker. For example, if we want to install spotgear and baker we can run:

osler_install(c("baker", "spotgear"))

Installing the oslerInstall package

The oslerInstall package contains the oslerLite/osler_install functions, as well as others relevant for OSLERinHealth. You can install the package as follows:


After installation, you can use oslerInstall::oslerLite() to install packages without source-ing the URL above.

Installing Stable/Current/Release Versions

Stable Versions

In OSLERinHealth, there are stable versions, which correspond to a submitted package. This stable version has passed the OSLERinHealth checks on Travis for Linux using the other packages in OSLERinHealth that are in OSLERinHealth at the time of submission. Thus, if you install this package with all the dependencies listed for this package (using specific OSLERinHealth versions), it should work.

To install a stable version (which should be the default), you can run:

osler_install(c("baker", "spotgear"), release = "stable")

Current Versions

In OSLERinHealth, a “current” version mirrors the repository of the developer of the package. This does not ensure that the package is passing OSLERinHealth checks, but will give you the development version from that developer. This, at least, standardizes the username for all the repositories in OSLERinHealth. You can install a current version using:

osler_install(c("baker", "spotgear"), release = "current")

Release Versions

Every few months, we snapshot all of OSLERinHealth in their current forms. We save the source tarballs as well as the binary releases from Travis and Appveyor. We then host these releases on the OSLERinHealth website. These downloads are stable in time and will not be changed until the next release. These downloads are also logged to show the activity/amount of use for each package of this release. To install the release, you would use:

osler_install(c("baker", "spotgear"), release = "release")

See the release_repo argument for how to specify which release to use.

oslerLite: an alias for osler_install

As Bioconductor uses the biocLite function to install packages, we have created a duplicate of osler_install, called oslerLite, for ease of use for those users accustomed to Bioconductor. The same command could have been executed as follows:

oslerLite(c("baker", "spotgear"))

Installing OSLERinHealth Packages without upgrading dependencies

The oslerLite/osler_install functions depend on devtools::install_github, which will upgrade dependencies by default, which is recommended. If you would like to install a package, but not upgrade the dependencies (missing dependencies will still be installed), you can set the upgrade_dependencies argument to FALSE:

oslerLite(c("baker", "spotgear"), upgrade_dependencies = FALSE)

Installing and starting R

  1. Download the most recent version of R from There are detailed instructions on the R website as well as the specific R installation for the platform you are using, typically Linux, OSX, and Windows.

  2. Start R; we recommend using R through RStudio. You can start R using RStudio (Windows, OSX, Linux), typing “R” at in a terminal (Linux or OSX), or using the R application either by double-clicking on the R application (Windows and OSX).

  3. For learning R, there are many resources such as Try-R at codeschool and DataCamp.

Packages not available on OSLERinHealth

If a package is not in the OSLERinHealth list of packages, then it is not located on the OSLERinHealth Github. Therefore, when installing, you’ll get the following error:

Error in osler_install(...) : 
  Package(s) PACKAGE_TRIED_TO_INSTALL are not in oslerinhealth

Once a package is located on the list of packages, then it will be available to install.
