r-help[Q]: use of `expression' in annotation
Alex Buerkle <cbuerkle at bio.indiana.edu> writes:
I would like petstring to contain r[rho*p] = peti, where peti is the corr. coefficient that would vary across panes in the figure. I have tried various combinations of paste and expression and have not hit on the right combination (instead I usually get peti as a literal rather than a variable).
Consider the following: plot(0:11,type='n') for (x in 1:10) text(x,x,as.expression(substitute(r[rho*p] == peti,list(peti=x/10)))) [which probably also indicates that the as.char.or.expr() function used inside text() could use modification! The as.expression bit should be avoidable on objects of mode call.]
