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.

Hi IS is data frame so it is not numeric. try str(IS) to see structure of your data. maybe just mat.IS <- as.matrix(IS) gives you desired result, but it depends on (undisclosed) IS structure BTW, do not use html formatting, it is useless in this list BTW2, you should spend at least few minutes to read basic docs, kindly offered by R-core in doc directory, especially R-intro which gives you quick info about objects and their properties. BTW3, your read.table is lacking header and sep and maybe dec specification so I doubt it reads your data properly.

To the OP: read.csv is a way to call read.table but deliberately made inflexible. It sets some arguments to values other than their defaults, including header = TRUE sep = "," fill = TRUE The default dec = "," is the same. If you are reading files coming from countries like mine where the decimal separator is a comma read.csv2 sets the values sep = ";" and dec = ",". Read help("read.csv"), the difference from read.table is well explained.
