Hi I am looking for a structural equation modeling package in R which can be used for categorical data. Is anyone aware of the existence of such a package? Would appreciate any help on this.

.... I do not need all the columns in the files. I want to extract only some columns from the .txt file or the .dat file, because reading the entire file is becoming very difficult due to memory issues.

Any information on this would be greatly appreciated. Thank you Upasna -- --------------------------------------------------------------------- Upasna Sharma Research Scholar Shailesh J.

Is there a way, I can retrieve the output that is not visible?

Hi I have a dataset (.txt file and .dat file) in which the length of one record is 144. There is no header in the .txt or .dat file itself. When I read this file using the read.table command, and want to drop some coloumns by setting the argument colClasses to "NULL" for the columns that I want to drop, it does not work, because the entire record of the length 144 is being treated as
