R help - May 2006 - plot sub/super-script, formulas in boxplots

Hi,

I try this one:

boxplot(dados[,5]~dados$Trat, xaxt = "n", ylab    
substitute(paste("mg de CO"[2],"/100 mL de
MC"),list(x="")))

and I get this one in ylab:

NA/100 mL de MC

If I try this one:

plot(1,2,
     xlab      substitute(paste("Arrival date 1 = May
1"^{st},"",list(x=""))),
     ylab      substitute(paste("mg de CO"[2],"/100 mL de
MC"),list(x="")))

I see this one in ylab:

mg de CO$_2$/100 mL de MC
        ^^^^^
        LaTeX because I dont know how I type sub in txt. I am sorry.

How I do the same in the boxplot? Or isnt possible?

Thank you very much

Marcelo

Try this:

boxplot(1:10, xaxt = "n", ylab = quote(mg ~ de ~ CO[2]/100 ~ mL ~ de ~
MC))
