semptools 0.2.10

New Features

Added auto_factor_point_to() for creating the factor_point_to matrix. Revised set_sem_layout() to allow users to use a named vector for the factor_point_to argument. (0.2.9.15)
Added auto_indicator_order() and lavaan_indicator_order() for setting indicator order in set_sem_layout() and set_cfa_layout(). Can handle nodes with labels changed. (0.2.9.18, 0.2.9.24)
Revised set_cfa_layout() and set_sem_layout() to set indicator_order and indicator_factor automatically if not supplied. Node labels must be string for this option to work. (0.2.9.18, 0.2.9.23)
Added an pkgdown articles on setting the layout for a model with both latent factors and exogenous observed variables. (0.2.9.25)

Fixed set_cfa_layout() to work for LISREL-style graphs. (0.2.9.13)
Fixed set_cfa_layout() to work for a model without factor covariances (e.g., exoCov = FALSE when calling semPlot::semPaths()). (0.2.9.14)
Fixed a bug in auto_factor_point_to(): Cells with no direction specified is now set to NA. (0.2.9.21)

Added an R CMD check for noSuggests. (0.2.9.12)
Fixed a bug in the setting for pkgdown. (0.2.9.16)
Add DoNotPlot = TRUE in all tests to prevent semPlot::semPaths() from plotting the graphs in the tests. (0.2.9.17, 0.2.9.20)
Added the helper add_object(). (0.2.9.18)
Removed dplyr functions from the code and removed dplyr from Imports. (0.2.9.19)
Removed the check for factors with no direction specified in auto_factor_point_to(). The “factor” may be a manifest variable without indicators. (0.2.9.20)
Added two internal helpers to check node labels (labels changed? labels non-string?). (0.2.9.22)
Removed the mention of change_node_label2, which was not exported, from the help page. (0.2.9.26, 0.2.9.27)
Made the warning and error messages of set_cfa_layout() and set_sem_layout() more informative. (0.2.9.28)

Used the native functions of semPlot (semPlot::man() and semPlot::lat()) to check nodes in drop_nodes() and keep_nodes(). As a consequence, the semPlot package is now in the Import section. (More native functions will be used in the future to ensure compatibility.) (0.2.9.11)

Added support for 2nd order factor (see vignette("second_order")). (0.2.9.7)
Fixed doc due to Roxygen updated to 7.2.1. (0.2.9.7)
Update the GitHub actions. (0.2.9.8)
Fixed doc due to Roxygen updated to 7.2.3. (0.2.9.9)
Fixed set_curve(). It should now work for bidirectional edges regardless of the order of the nodes in the specification. (0.2.9.9)

Updated drop_nodes(): It now works with output without a covariance matrix (e.g, a model generated from lavaan::lavaanify() without data).

Fixed a bug in set_sem_layout(). Failed to work with models in which all factors have the same number of indicators.

Reformatted the help sections of the functions (wrap the text for readability). This has no impact on uses and the generated help files.

Added drop_nodes() and keep_nodes(). They process a semPlotModel object, which is generated by semPlot::semPlotModel(), drop or keep selected nodes (e.g., observed variables, latent factors) from the object. The result can then be passed to semPlot::semPaths() to draw a diagram without the dropped nodes.
Add layout_matrix. A helper function for creating a layout matrix to be used by semPlot::semPaths(). Users specify the positions of nodes and the function will create the matrix accordingly.
mark_sig(), mark_se(), and set_cfa_layout() will raise an error if the semPlot::semPaths object has intercepts terms. These function do not support plots with intercept terms yet.
Updated change_node_label() to support named vectors.
Added vignette("layout_matrix") to explain how layout matrix is used in semPlot::semPaths(), and how layout_matrix() can be used to construct the layout matrix.
Updated the vignettes to use named vectors instead of “list of named lists” in some functions.
Updated vignette("semptools") to introduce change_node_label().
magrittr is no longer required for installing the package.

Added change_node_label() for changing the labels of nodes. Several other functions were modified to adapt for this function.
Added to_list_of_lists() for converting a named vector to a list of lists. Specifying a list of lists is necessary in some cases because the a label may not be string (e.g., it may be an expression). However, in most cases, all elements are strings or numbers and so a named vector will do. This function is to be used internally by other functions, not to be used by users.

Fix a bug in set_cfa_layout(). It now will not raise an error for one-factor models.
Fix some typo errors in documentation pages.

Import the pipe operator from magrittr so users no need to load the package themselves.

Update the documentation of mark_sig() and mark_se() to emphasize that currently they require a lavaan output.
