fa.parallel function not found

[pragya4104]

I am trying to run parallel analysis in factor analysis using the below equation.

parallel<-fa.parallel(e, fm='minres', fa='fa')

its showing me the following error-
Error in fa.parallel(e, fm = "minres", fa = "fa") :
could not find function "fa.parallel"

Have you load the from where the function is from ?

[pragya4104]

Yes the package is -psych and i have already downloaded it

You need a library(psych) to load it before using it after you installed it with ˋinstall.packages`

[pragya4104]

parallel <- fa.parallel(e, fm = 'minres', fa = 'fa')
Error in eigen(rx) : infinite or missing values in 'x'
In addition: Warning message:
In cor(x, use = use) : the standard deviation is zero

Now showing this error

We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
