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.
Since the file is a csv file (or at least its extension is) read.csv
should solve those issues.
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.
Hope this helps,
Rui Barradas

Subject: [R] paran package - error message
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.
