Dear André, The components of the "sem" object returned by sem() are explained on the help page ?sem. There are several methods for "sem" objects:
> methods(class="sem") [1] mod.indices.sem* normalized.residuals.sem* [3] path.diagram.sem* print.sem* [5] residuals.sem* standardized.residuals.sem* [7] summary.sem* To retrieve components of the object directly, just use, e.g., object$C (for the reproduced covariance matrix), or object$coeff (for estimates of free parameters), in the normal manner for indexing a list. It would probably be better for me to provide accessor functions [e.g., for the coef() generic] for at least some of these, so I'll put that on the list of things to do. I hope this helps, John -------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox -------------------------------- > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of andre > tavares correa dias > Sent: Tuesday, February 07, 2006 12:28 PM > To: [email protected] > Subject: [R] elements from 'sem' function > > Hi, > I would like to print elements from sem (structural equation > modeling) function (e.g., model-reproduced covariance matrix > (C); estimated asymptotic covariance matrix of parameter > estimates (cov)). > > How can I do this? > > Thanks, > André > > -- > André Tavares Corrêa Dias > Laboratório de Ecologia Vegetal > Universidade Federal do Rio de Janeiro > CCS-IB-Departamento de Ecologia > Caixa Postal 68020 > 21941-970 Rio de Janeiro RJ, Brazil > tel: +55 21 25626377 > Fax: + 55 21 25626320 > [EMAIL PROTECTED] > > ______________________________________________ > [email protected] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! > http://www.R-project.org/posting-guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
