Peculiar behaviour with MatchIt and a function
Folks,
I have a strange situation where:
library(MatchIt)
f <- function(d) {
m <- matchit(treatment ~ lsales + major.industry,
data=d, method="nearest", discard="hull.treat")
treatmentfirms <- match.data(m, group="treat")
list(m=m, treatmentfirms=treatmentfirms)
}
res <- f(ex)
does not work at the match.data() call, while the identical lines within f() --
m <- matchit(treatment ~ lsales + major.industry,
data=ex, method="nearest"...
