# semhelpinghands 

(Version 0.1.12.1 updated on 2025-11-22, [release history](https://sfcheung.github.io/semhelpinghands/news/index.html))

This package is an assortment of time-saving helper functions for doing structural

equation modeling

(SEM), mainly by `lavaan::lavaan()` and its wrappers, such as

`lavaan::sem()` and `lavaan::cfa()`. This package is not for implementing

advanced statistical procedures. This should be the job of excellent

packages such as `semTools`. These helper functions are for tasks that come

in handy (at least to me) when doing SEM. They are

usually used *during* the data analysis phase, not for publishing

or presenting results.

Many of the tasks can be done by base R code or by `dplyr` functions.

However, these functions may help users who are not familiar with

R programming or use R only occasionally to do these tasks

without writing their own code, or for people like me who know

how to do this using base R but do not want to write the code every

time.

I intentionally use base R if possible because I want to keep

`semhelpinghands` a light weight package, depending on as few

other packages as possible, so that I do not need to worry about

deprecated functions or updates in other packages that break things,

defeating the "time saving" purpose of this package.

# Home Page

More about this package can be found from the GitHub page of this package:

[https://sfcheung.github.io/semhelpinghands/](https://sfcheung.github.io/semhelpinghands/)

# Installation

The latest version at CRAN can be installed by `install.packages()`:

```

install.packages("semhelpinghands")

```

The latest developmental version at GitHub can be installed by `remotes::install_github()`:

```

remotes::install_github("sfcheung/semhelpinghands")

```

# Motive

One major motive behind all these functions

is writing something for my own work

with others. So,

each function should be at least useful

to me myself and I myself will use them.

Nevertheless, maybe there are others

who, like me, just want some simple

functions for some simple tasks. I

also like using packages to pack functions

I used myself in my work, so I do not have to

source files again and again. Therefore,

I packaged them into `semhelpinghands`

also for myself.

I hope this package will also be useful

for some others.

I will only devote a limited amount of

time on this package. The package and

its functions are means for me to do

research. They are not the goals

themselves.

# Acknowledgement

I would like to thank Prof. Rosseel and

Prof. Jorgensen for developing `lavaan`

and `semTools`. Their advice in the

[lavaan Google Group](https://groups.google.com/g/lavaan?pli=1)

and GitHub pages (for [lavaan](https://github.com/yrosseel/lavaan)

and [semTools](https://github.com/simsem/semTools))

on various issues about `lavaan`

helped me in writing some

of the functions here, before they

were packed into `semhelpinghands`.

If there are people who inspired some

of the functions but I forgot to acknowledge,

please let me know.

# Suggestions and Bugs

This package is still under development.

There will be bugs, and there are

limitations. Comments and suggestions

are welcomed. Feel free to add an issue

at [GitHub](https://github.com/sfcheung/semhelpinghands/issues).

Although I may not be able to address

all of them because this package is

intended to be a collection of simple

functions for simple tasks, and

they are designed

to be easy to maintain, I will try to

do what I can do.
