mkdirs: Creates a directory including any necessary but nonexistent parent directories
Description
Creates a directory including any necessary but nonexistent parent directories.
Usage
"mkdirs"(pathname, mustWork=FALSE, maxTries=5L, ...)
Arguments
pathname
A character string of the pathname to be checked. mustWork
If TRUE and the directory does not already exists or
is failed to be created, an error is thrown, otherwise not. maxTries
A positive integer specifying how many times the
method should try to create a missing directory before giving up. Value
Returns TRUE if the directory was succesfully created,
otherwise FALSE.
Note that if the directory already exists, FALSE is returned.
Slow file systems
On very rare occassions, we have observed on a large shared file
system that if one tests for the existence of a directory immediately
after creating it with dir.create(), it may appear not
to be created. We believe this is due to the fact that there is a
short delay between creating a directory and that information being
fully propagated on the file system. To minimize the risk for such
false assertions on "slow" file systems, this method tries to create
a missing directory multiple times (argument maxTries) (while
waiting a short period of time between each round) before giving up.
