combine.spacegraphs: Combine two spacegraph objects.

In cem: Coarsened Exact Matching

Combine two spacegraph objects.

Description

Combine two spacegraph objects so that their results can be plotted together. Both spacegraphs must be from the same dataset using the same distance metric.

Usage

combine.spacegraphs(x,y) 

Arguments

x	a spacegraph object to be combined
y	a spacegraph object to be combined

Details

This allows users to combine two spacegraph objects rather than having to re-run the spacegraph command from the start.

Inputs must be created using spacegraph.

Value

val	an object of class spacegraph.

Examples

data(LL)
set.seed(123)
sp1 <- spacegraph("treated", LL, drop="re78", M=5,
                  R=list(cem=5,psm=5, mdm=0))

## Note that we must use the same L1 measure from the first spacegraph!
sp2 <- spacegraph("treated", LL, drop="re78", raw.profile=sp1$raw.profile,
                  R=list(cem=0,psm=0, mdm=5))

sp3 <- combine.spacegraphs(sp1,sp2)

plot(sp3)
