Factor Analysis and Correlations in R using Simple Script or ProjectTemplate: Example Exercise
Data and Scripts: github.com/jeromyanglim/simple-correlation-factanal-exercise
This is a simple exercise in R showing how to run a factor analysis, some correlations, and look at some group differences in R. It scores the test and produces some basic output. The emphasis is on how to organise the code using a simple script or using ProjectTemplate.

p value is 0.00 that means this model is not fit. How will you transform the model inti fit
I am an expert in this, should anyone need more explanation. Kindly reach out.
This was an excellent video !!! Learned how to compare correlated and non-correlated models.
Dude, you're insane!!!!!
Thank you for this. I'm using data from questionnaires to test whether self-esteem, self-efficacy, risk taking behaviour and personal growth positively or negatively predict anxiety. I'm in the process of working out the most appropriate statistical test and I think this is the one I need. Thanks again
This is a fantastic review!!
Hello, Prof. Anglim, thanks for your nice and high proficient videos. I am just get into R, I am not sure, how could we do Validity check, AVE, MSV, FORNELL-LARCKER-RATIO check in R? thanks for answering question in advance, wish you a lovely day.
Great talk! I'm very impressed with highcharter; seems very clean
Thanks for the lecture professor
lol I searched for survey analysis and this popped up in my recommended videos one week after
Incredibly clear, brilliant
Hi Dr. Jeromy, inside the config file you have an extra "v" for the Lavaan package. I couldn't understand why the 'ProjectTemplate' command wouldn't load especially since the package installed correctly. I thought I should mention it just in case others are new like myself. Thanks for this training, btw!
dude, thank you so much for the upload, it'll really help for this assignment I have <3
I wish the camera could just focus on the screen🙄
I’m really happy that you can so effortlessly click through RStudio and display your great uncommunicated awareness of the layout functionality and the fact that one needs to access specific data sets and libraries from some well-kept secret place using some very special clicks that only you are aware of. Please don’t call your video an “Introduction to Lavaan” when you’re not up to taking the time and effort to appreciate that what seems self-explanatory to you, is not for the novice. Unless, of course, there’s something like a “Absolute Introduction to Lavaan” in your mind.
rmm, this is an introduction to lavaan, not an introdution to R
Informative!!
not matched with the title
This is very useful! Thank you very much, Sir!
Hi. Cant run PorjectTemplate. ErrorMessage: one or more mandatory directories are missing. . quietstop()
tnx, is there a version for R4.0?

Hi did you chose with item to put 1*? sorry, i Didi not understand.
great work !!
Hi dear Jeromy Thanks for your excellent video on application of R in various statistical analyses! I wrote my R codes in Markdown, but when I tried to convert codes to HTML, showed this error: Error in .External2(C_loadhistory, file) : 'loadhistory' can only be used in Rgui and Rterm Calls: <Anonymous> Execution halted and for PDF showed this one: Error in .External2(C_loadhistory, file) : 'loadhistory' can only be used in Rgui and Rterm Calls: <Anonymous> Execution halted No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: @t If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex() Otherwise consider MiKTeX on Windows - @t MacTeX on macOS - @t (NOTE: Download with Safari rather than Chrome strongly recommended) Linux: Use system package manager could you please help to resolve this problem? of course, I have TinyTeX on my computer. best regards, Asghar
Thank you so much for this clear explanation, it has helped me enourmously!
Content is great and relevant, although the presentation video may not be made to fit UA-cam.
How to represent a random variable in R and random variable square (R^2) ?
Sir please provide the link of file used for analysis so that I can do it own.
Great video! I'd like to know more about the interpretation of the output. E.g., here www.understandingdata.net/2017/03/22/cfa-in-lavaan/#output they say the following: "The next kind of operator in the table is ~~. This means covariance, or, when it’s between a variable and itself, variance. The variances of observed variables are the error variances"... Is that so? if that is, can I drop items with the largest values on that?... is there any interpretation of what is considered large or small error variance?.... etc.
Thank you for posting these workshop resources. Very generous of you and much appreciated!
and how about Rorschach test and Excel and other clinical tests

I appreciate this video. Thank you so much!
Hi Jeromy, I got problem right from start, see below: > library(ProjectTemplate); load.project() Error in library(ProjectTemplate) : there is no package called ‘ProjectTemplate’ > # Initialise Project > ```{r knitr_configuration} Error: attempt to use zero-length variable name > library(knitr) Error in library(knitr) : there is no package called ‘knitr’ > opts_knit$set(root.dir = normalizePath('../')) # required when rmd is in subdirectory Error: object 'opts_knit' not found > ``` Error: attempt to use zero-length variable name > > ```{r load_project} Error: attempt to use zero-length variable name > library(ProjectTemplate); load.project() Error in library(ProjectTemplate) : there is no package called ‘ProjectTemplate’ > ``` Error: attempt to use zero-length variable name >Do I need to install something first! Would be thankful for your help!
What should I do if some regression weights are insignificant (P>.05) ? Should I delete the observed variable?
Thanks for the video! Very helpful
Good to see something about R packages without Rstudio which (most irritatingly) seems to have taken over the R world. I make my packages this way and this video (in spite of the quality) is very useful.
Awesome! Helped a lot!!
Hi, when tray to run "install.packages('ProjectTemplate')" in your project get this error "Current Directory: reports is not a ProjectTemplate directory , Please change to correct directory and re-run load.project()" do you know what happens? thks
try adding the "cache" directory. An update has now made this required.
you might not have done : # System Requirements * Install R cran.rstudio.com/ * Install Rstudio www.rstudio.com/products/rstudio/download3/ * Install R packages: `knitr`, `ProjectTemplate` (e.g., `install.packages("knitr")`) * Install any R packages required for data import or listed in `config/global.dcf`
Amazing!
where did we can down load your ppt
Shitty video quality
thanks for shared!
