This emulates ParamSetCollection$new(sets), except that the result is a flat ParamSet, not a ParamSetCollection.
The resulting object is decoupled from the input ParamSet objects: Unlike ParamSetCollection, changing $values of
the resulting object will not change the input ParamSet $values by reference.
This emulates ParamSetCollection$new(sets), which in particular means that the resulting ParamSet has all the Domains
from the input sets, but some $ids are changed: If the ParamSet is given in sets with a name, then the Domains will
have their <id> changed to <name in "sets">.<id>. This is also reflected in deps.
The c() operator, applied to ParamSets, is a synony for ps_union().
Arguments
- sets
(
listofParamSet)
This may be a named list, in which case non-empty names are prefixed to parameters in the correspondingParamSet.- tag_sets
(
logical(1))
Whether to add tags of the form"set_<set_id>"to each parameter originating from a givenParamSetgiven with name<name in "sets">.- tag_params
(
logical(1))
Whether to add tags of the form"param_<param_id>"to each parameter with original ID<param_id>.
Examples
ps1 = ps(x = p_dbl())
ps1$values = list(x = 1)
ps2 = ps(y = p_lgl())
pu = ps_union(list(ps1, ps2))
# same as:
pu = c(ps1, ps2)
pu
#> <ParamSet(2)>
#> id class lower upper nlevels default value
#> <char> <char> <num> <num> <num> <list> <list>
#> 1: x ParamDbl -Inf Inf Inf <NoDefault[0]> 1
#> 2: y ParamLgl NA NA 2 <NoDefault[0]>
pu$values
#> $x
#> [1] 1
#>
pu$values$x = 2
pu$values
#> $x
#> [1] 2
#>
# p1 is unchanged:
ps1$values
#> $x
#> [1] 1
#>
# Prefixes automatically created for named elements.
# This allows repeating components.
