Hi Maria, Thanks! I just happened to read this but normally don't read r-help. It is best to send specific questions on not well known packages to the maintainer directly.
The example on my website is hardcoded in the package. I should really also add the option to make a legend like you want though. But what you could do is create a dummy graph with the same parameters to get the color en width of the lines and then just add that as a legend. The graphs are just base R graphics so you could add a legend directly to it or plot it in a separate panel using layout(), e.g.: library("qgraph") # Dummy plot to extract edge coloring: g <- qgraph(cbind(1:4,1:4,c(0.4,0.6,0.8,1)),esize=7,gray=TRUE,maximum=1.4,cut=0.0001,DoNotPlot=TRUE) # Colors: col <- g$graphAttributes$Edges$color # lwd: lwd <- g$graphAttributes$Edges$width # Original plot: qgraph(Edges2,esize=7,nsize=12,gray=TRUE,layout="circular",filetype="pdf",width=5,height=5,vsize=11,label.prop=1.2,arrows=FALSE,border.color=c("red","red","blue","green","purple"),border.width=4,maximum=1.4,cut=0.0001) # Add legend: legend("topright",legend=c(0.4,0.6,0.8,1),col=col,lwd=lwd,bty="n") Best, Sacha --- Sacha Epskamp, MSc Department of Psychological Methods University of Amsterdam Weesperplein 4, room 2.05 1018 XA Amsterdam The Netherlands http://www.sachaepskamp.com 2013/7/31 María Antonieta Sánchez Farrán <antos...@gmail.com> > Hello R community, > > I am creating some network representations using the qgraph package (big > thanks to Sacha Epskamp for developing it!).
