?mtext shows you that "adj" really only uses one number, i.e., in your
case 0.5 = the default ...
[one could argue it should give a warning in your case..]
I don't see any problem;
here is some illuminating code :
eval(ex <- quote(par(oma=c(3,3,.2,.2))))
plot(1); mtext(deparse(ex))
box("inner", lty="dashed", col = "light blue")
for(a in seq(-.1,1.1,by=.1)) {
mtext(expression(sigma),1, outer=TRUE, adj= a)
mtext(format(a), 1,line=1, outer=TRUE, adj= a)
}
