Get The Conditional Indirect Effect for One Row of 'cond_indirect_effects' Output
Source:R/get_indirect_effect.R
get_one_cond_indirect_effect.Rd
Return the conditional
indirect effect of one row of the
output of cond_indirect_effects()
.
Arguments
- object
The output of
cond_indirect_effects()
.- row
The row number of the row to be retrieved.
Value
An indirect
-class object,
similar to the output of
indirect_effect()
and
cond_indirect()
. See
[indirect_effect)] and
cond_indirect()
for details on
these classes.
[indirect_effect)]: R:indirect_effect)
cond_indirect()
: R:cond_indirect()
Details
It just extracts the
corresponding output of
cond_indirect()
from the requested
row.
