| lazyLoad {base} | R Documentation |
Lazy load a database of R objects.
lazyLoad(filebase, envir = parent.frame(), filter)
filebase |
The file path to the database, with no extension. |
envir |
The environment into which objects are loaded. |
filter |
An optional function which when called on a a character vector of object names returns a logical vector: only objects for which this is true will be loaded. |
This is the workhorse function called by the package loader to load the code for a package from a database. The database consists of two binary files, ‘filebase.rdb’ (the objects) and ‘filebase.rdx’ (an index).
The objects are not themselves loaded into envir: rather
promises are created that will load the object from the database on
first access. (See delayedAssign.)
