[R] YNT: ggtern and bquote...

Hi,

My example code is this;

x11<-data.frame(A=c(.6,.6,.6),B=c(.20,.20,.20),C=c(0.20,.20,.20))
ggtern(data=x11,aes(A,B,C,xend = c(0.7,.00,0.7),yend = c(.30,.50,.0),zend
=c(.0,.50,0.3)))+
    geom_point()+
    theme_showarrows()+geom_segment(size=.5)+

geom_text_viewport(x=c(.45,.27,.37),y=c(.32,.29,.22),label=as.expression("P_a","P_b","P_c"))

ggtern(data=x11,aes(A,B,C,xend = c(0.7,.00,0.7),yend = c(.30,.50,.0),zend
=c(.0,.50,0.3)))+
    geom_point()+
    theme_showarrows()+geom_segment(size=.5)+

geom_text_viewport(x=c(.45,.27,.37),y=c(.32,.29,.22),label=as.expression(quote(c("P_a","P_b","P_c"))))

In geom_text_viewport (I also tried geom_label and geom_text versions) tried all
possible solutions, but i couldn't achieved. R command outputs are like
this:

Error in stats::complete.cases(df[, vars, drop = FALSE]) :
  invalid 'type' (expression) of argument

Maybe i am writing the code wrong, i couldn't figure out.

Thanks for your kind answers.

Yes, I vaguely remember that indeed also for the lattice package
(which is based on 'grid' the same as 'ggplot2' is ..) sometimes
expressions instead of calls are needed, i.e., expression(*)
instead of just quote(*).

However, I think Levent really meant what you'd get by
 expression(P[a]) ?

@Levent: The clue is the need for valid R syntax, and indeed, as
   in LaTeX  x_i often is the i-th element of x,  the R syntax for
   indexing/subsetting is used here, i.e.
    x[i]  for LaTeX  x_i

Last but not least, if Levent really needs bquote() [i.e. substitute()]
then, a final
      as.expression(.)
may be needed :

identical(as.expression(quote(a == 1)),
             expression(      a == 1))  # --> TRUE

D'oh! Thanks for pointing this out. I blame caffeine depletion at the
