batchExpandGrid {BatchJobs} | R Documentation |
Map function over all combinations.
Description
Maps an n-ary-function over a list of all combinations which are given by some vectors.
Internally expand.grid
is used to compute the combinations, then
batchMap
is called.
Usage
batchExpandGrid(reg, fun, ..., more.args = list())
Arguments
reg |
[ |
fun |
[ |
... |
[any] |
more.args |
[ |
Value
[data.frame
]. Expanded grid of combinations produced by expand.grid
.
Examples
reg = makeRegistry(id = "BatchJobsExample", file.dir = tempfile(), seed = 123)
f = function(x, y, z) x * y + z
# lets store the param grid
grid = batchExpandGrid(reg, f, x = 1:2, y = 1:3, more.args = list(z = 10))
submitJobs(reg)
waitForJobs(reg)
y = reduceResultsVector(reg)
# later, we can always access the param grid like this
grid = getJobParamDf(reg)
cbind(grid, y = y)
