testDataPath
Find Data Files for Tests in SNTEST/Data Directory
Description
Return the path to a data file stored under Sys.getenv("SNTEST")/Data.
Usage
testDataPath(..., SNTEST = testGetSNTEST())
testSetSNTEST(SNTEST)
testGetSNTEST()
testCheckSNTEST(SNTEST)
Arguments
| ... |
The file name, relative to SNTEXT/Data. If it is
in a subdirectory of SNTEXT/Data then split up its
name into path elements (e.g., use testDataPath("excel",
"t1.xls") instead of testDataPath("excel\t1.xls")).
|
| SNTEST |
The home directory of SNext. Its Data directory
should contain the data files.
|
Details
The default value of SNTEST is taken from the environment
variable SNTEST, which may be set from outside or inside
of R. testSetSNTEST() and testGetSNTEST() set
and get that variable and also call testCheckSNTEST()
to check that it looks like a valid value (or throw
an error if not).
Currently that means that SNTEST and SNTEST/Data
are both directories.
Value
testDataPath() returns a path to the data file that can
be used by any R function that requires a file name.
Note
These functions stop if the directories or files requested
do not exist.
