Hello, I still have my problem. I couldn't make Uwe Ligges's example work. I wonder why :-(
The following doesn't work : param.list=list(mu1=0,mu2=0,s1=3,s2=2,s3=2,s4=4) plot(1:8,type="n") text(8,3,adj=1,labels=substitute("with " * mu == bgroup("(",atop(mu1,mu2),")") * "," * Sigma[x] == bgroup("(",atop(s1~~s3,s2~~s4),")"),param.list)) But this works : plot(1:8,type="n") text(8,3,adj=1,labels=substitute("with " * mu == bgroup("(",atop(mu1,mu2),")") * "," * Sigma[x] * "=" * bgroup("(",atop(s1~~s3,s2~~s4),")"),param.list)) So like in my problem the problem seems to be ==.
