Beginning Steps
> #read the dataset into R variable using the read.csv(file) function
> data <- read.csv("dataset_EFA.csv")

Psych Package
> #install the package
> install.packages("psych")
> #load the package
> library(psych)

Factor Solution
> #calculate the correlation matrix
> corMat <- cor(data)
> #display the correlation matrix
> corMat

> #use fa() to conduct an oblique principal-axis exploratory factor analysis
> #save the solution to an R variable
> solution <- fa(r = corMat, nfactors = 2, rotate = "oblimin", fm = "pa")
> #display the solution output
> solution
