Sourcing extensions

Functions for extending sourcing features

Usage

ksource(file, ..., quiet = TRUE, cd = FALSE, env = parent.frame())

try_source(file, cd = FALSE, ...)

try_ksource(file, ...)

Arguments

file

An R or Rmd file.

...

Additional arguments passed to base::source()

quiet

Logical; Determines whether to apply silence to knitr::purl()

cd

Logical; if TRUE, the R working directory is temporarily changed to the directory containing file for evaluating

env

An environment determining where the parsed expressions are evaluated

Value

• ksource(): Invisibly, the result of calling source() on the .R file conversion of file

• try_source(), try_ksource(): attempts of source() and ksource() but converts errors to warnings

Details

try_source() will output an error message rather than completely preventing the execution. This can be useful for when a script calls on multiple, independent files to be sourced and a single failure shouldn't prevent the entire run to fail as well.
