Test() reloads your code, then runs all testthat tests. load_all() will automatically create a DESCRIPTION if needed.ĭocument() updates documentation, file collation and NAMESPACE. During development you usually want to access all functions so load_all() ignores the package NAMESPACE. Load_all() simulates installing and reloading your package, loading R code in R/, compiled shared objects in src/ and data files in data/. If you don't specify a path, devtools will look in the current working directory - this is recommend practice. # Remove the package after installation unlink( "devtools.zip")Īll devtools functions accept a path as an argument, e.g. Install.packages( "devtools.zip", repos = NULL) Mac and Linux: devtools:: install_github( "hadley/devtools")
