Description Usage Arguments Details Value Examples
This function reliably tries to attach a package and silently returns FALSE
if the package cannot be attached. Unlike require
, it does not generate an error if the package exists but cannot be attached (e.g., because of version requirements).
1 | tryRequire(what)
|
what |
The name of the package |
The function intends to run silently, but this is not uniformly possible, since the quietly = TRUE
option to require()
does not suppress messages from other packages attached through dependencies in this package.
The value is not returned invisibly, as it would be with require()
.
TRUE
if the package was successfully attached and FALSE
otherwise.
