BTW3, your read.table is lacking header and sep and maybe dec specification so I doubt it reads your data properly. Cheers Petr

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. Deborah D. Lee, PhD Associate Director of Student Affairs Research and Assessment The Pennsylvania State University 105 White Building University Park, PA 16802 (814) 863-9609 [[alternative HTML version deleted]]
