umx_parameters: 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. umx_parameters 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.

Usage

umx_parameters(x, thresh = c("all", "above", "below", "NS", "sig"),
  b = NULL, pattern = ".*", std = FALSE, digits = 2)
umxParameters(x, thresh = c("all", "above", "below", "NS", "sig"), b = NULL,
  pattern = ".*", std = FALSE, digits = 2)
parameters(x, thresh = c("all", "above", "below", "NS", "sig"), b = NULL,
  pattern = ".*", std = FALSE, digits = 2)

Arguments

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

thresh

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

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("One Factor", data = mxData(demoOneFactor, type = "raw"),
	umxPath(from = "G", to = manifests),
	umxPath(v.m. = manifests),
	umxPath(v1m0 = "G")
)
# Parameters with values below .1
umx_parameters(m1, "below", .1)
# Parameters with values above .5
umx_parameters(m1, "above", .5)
# Parameters with values below .1 and containing "_to_" in their label
umx_parameters(m1, "below", .1, "_to_")
# }
