Run Jobs Interactively

Starts a single job on the local machine.

testJob(id, external = FALSE, reg = getDefaultRegistry())

Arguments

id	[integer(1) or data.table] Single integer to specify the job or a data.table with column job.id and exactly one row.
external	[logical(1)] Run the job in an external R session? If TRUE, starts a fresh R session on the local machine to execute the with execJob. You will not be able to use debug tools like traceback or browser. If external is set to FALSE (default) on the other hand, testJob will execute the job in the current R session and the usual debugging tools work. However, spotting missing variable declarations (as they are possibly resolved in the global environment) is impossible. Same holds for missing package dependency declarations.
reg	[Registry] Registry. If not explicitly passed, uses the default registry (see setDefaultRegistry).

Value

Returns the result of the job if successful.

tmp = makeRegistry(file.dir = NA, make.default = FALSE)
#> No readable configuration file found
#> Created registry in '/tmp/batchtools-example/reg' using cluster functions 'Interactive'
batchMap(function(x) if (x == 2) xxx else x, 1:2, reg = tmp)
