logger.validate.file: logger.validate.file

In RnBeads: RnBeads

Description

Validates the specified file or directory exists. Prints an error or a warning message to the log if it does not exist, it is not of the accepted type or is not accessible.

Usage

logger.validate.file(file, is.file = TRUE, terminate = TRUE)

Arguments

file	Name of file or directory to validate.
is.file	Flag indicating if the given name must denote an existing file. If this is FALSE, the given name must denote a directory. Set this to NA if both types are an acceptable scenario.
terminate	Flag indicating if the execution is to be terminated in case the validation fails. This parameter determines if an error message (terminate is TRUE) or a warning message (terminate is FALSE) is to be sent to the log when the specified file or directory does not exist, is not of the accepted type or is not accessible.

Value

Whether the validation succeeded or not, invisibly. Note that when terminate is TRUE and the validation fails, the R session is closed and thus no value is returned.
