Forgive me if I'm posting to the wrong place....It's my first time posting.
Here's the situation: I'm using the sem package and making path diagrams using path.diagrams. Suppose I have the following code: #install.packages("ggm") require(ggm) cor = rcorr(7) nm = c("SOF", "IWF", "PWF", "FSC", "FSF", "EF", "GPA") ram = specify.model() PWF -> FSF, a, NA PWF -> FSC, b, NA SOF -> FSF, c, NA SOF -> FSC, d, NA IWF -> FSF, e, NA IWF -> FSC, f, NA FSC -> EF, g, NA FSF -> EF, h, NA EF -> GPA, i, NA PWF <-> IWF, j, NA PWF <-> SOF, k, NA SOF <-> IWF, l, NA PWF <-> PWF, d1, NA SOF <-> SOF, d2, NA IWF <-> IWF, d3, NA FSC <-> FSC, d4, NA FSF <-> FSF, d5, NA EF <-> EF, d6, NA GPA <-> GPA, d7, NA sem.mod = sem(ram, cor, N=1656, obs.variables=nm) path.diagram(sem.mod, 'path/to/file/plot', ignore.double=FALSE, edge.labels="values", standardize=TRUE, min.rank=c("IWF", "SOF", "PWF")) The diagram is produces is hard to read because of the many variances that are shown. The covariance estimates are important for my diagram, but the variances are not. Is there a way to suppress the variance arrows without suppressing the covariance arrows? -- Dustin Fife Graduate Student, Quantitative Psychology University of Oklahoma ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
