[R] Matching package argument exact

[Kathrin Müller]

Hi,

I’d like to do some sample matching with propensity scores. I’ve estimated
the propensity scores:

glm1 <-
glm(Exposed~Gender+ImagingCentreID+espad.3a+drinks.preg+espad.6+audit.total+
PDS.all, family=binomial, data=PBQ_110421)

Now I would like to match on the propensity score and have an exact match on
Gender and ImagingCentreID. How do I specify this in the command:

M1 <-Match(Tr = Exposed, X = glm1$fitted) ?

Sorry, if my question is trivial! But I am an absolute beginner in R.

Thanks,
Kathrin
