umx (version 4.0.0)

umxParameters: Display path estimates from a model, filtering by name and value.

Description

Often you want to see the estimates from a model, and often you don't want all of them. umxParameters() helps in this case, allowing you to select parameters matching a name filter, and also to only show parameters above or below a certain value.

If pattern is a vector, each regular expression is matched, and all unique matches to the whole vector are returned.

Usage

umxParameters(
  x,
  thresh = c("all", "above", "below", ">", "<", "ns",="" "sig"),="" b="NULL," pattern=".*" ,="" std="FALSE," digits="2" )<="" p="">

parameters( x, thresh = c("all", "above", "below", ">", "

Arguments

x

an mxModel() or model summary from which to report parameter estimates.

thresh

optional: Filter out estimates 'below' or 'above' a certain value (default = "all").

b

Combine with thresh to set a minimum or maximum for which estimates to show.

pattern

Optional string to match in the parameter names. Default '.*' matches all. regex() allowed!

std

Standardize output: NOT IMPLEMENTED YET

digits

Round to how many digits (2 = default).

Value

  • list of matching parameters, filtered by name and value

Details

It is on my TODO list to implement filtering by significance, and to add standardizing.

Examples

Run this code
# NOT RUN {
require(umx)
data(demoOneFactor)
manifests = names(demoOneFactor)
m1 = umxRAM("OneFactor", data = demoOneFactor,
	umxPath(from = "G", to = manifests), # factor loadings
	umxPath(v.m. = manifests),           # residual variance
	umxPath(v1m0 = "G")                  # standardized latent
)
# Parameters with values below .1
umxParameters(m1, "below", .1)
# Parameters with values above .5
umxParameters(m1, "above", .5)
# Parameters with values below .1 and containing "_to_" in their label
umxParameters(m1, "below", .1, "_to_")
# }
