readRDSfile

ReadRDSfile is not a standard function in base R. In the R programming language, the canonical way to read a single object from a file created with saveRDS is readRDS. Some packages or project code may introduce a function named readRDSfile, typically as a wrapper or alias to readRDS, or as a convenience function to emphasize file-based reading.

When present, readRDSfile generally returns a single R object and accepts the same core arguments as readRDS, most commonly the file parameter and an optional refhook parameter used to control how references within the object are reconstructed. The exact behavior can vary if a package defines it differently, so consulting the package documentation is advisable.

Important distinctions include the format and scope. readRDSfile, like readRDS, reads data saved with saveRDS and returns only one object. It does not load multiple objects or restore an entire workspace as load does with .RData files. The RDS format is specific to R, meaning objects serialized with saveRDS are generally intended for use within R and may not be portable to other languages without special tooling. As with all deserialization, reading from untrusted sources should be avoided to prevent security risks, such as executing code embedded in the serialized object.

Examples of usage (assuming readRDSfile is defined similarly to readRDS): obj <- readRDSfile("model.rds"). See also readRDS, saveRDS, load, and the RDS file format.
