I am trying to using the "paran" package in R for Horn's parallel analysis.
According to the "paran" manual, the highlighted yellow ought to be a numerical
matrix or data frame. It looks like this should be the file name. Is there
something that I need to do
install.packages("paran")
library(paran)
IS<- read.table ("C:/Users/Deborah Lee/Documents/R/IS.csv")
paran(IS, cfa=TRUE, graph=TRUE, color=TRUE, col=c("black", "red", "blue"))
When I run the code above, I get the error message below.
in cor(x) : 'x' must be numeric
How do I set up my data (csv) file itself to make this a numerical matrix?
(FYI: row 1 for headers for variables names).
Thank you for your help.
