HS.model <- ' visual  =~ x1 + x2 + x3
              textual =~ x4 + x5 + x6
              speed   =~ x7 + x8 + x9'
# fit the model to the data
fit <- cfa(HS.model, data=HolzingerSwineford1939)
# get the modification indices
mi_model <- modindices(fit, minimum.value = 10, sort = TRUE)
# look for x9 related modification indicies
lavaanMIExtract(RelevantVariable = "x9",
                lavaanMIObject = mi_model,
                sortByMI = TRUE)
