Hi all,
I asked something like this earlier but decided that a proper minimal
example might be helpfull ;0)
Why does this work with regards to the expression (substitution):
require(stats)
plot(cars)
text(5,120,labels=substitute(i^{z+phantom()}*"("*a*"
AMU)",list(i="yx",z=2,a=0)))
text(c(5,5),c(115,110),labels=c("One","Two"))
But adding this (using a vector of expressions/substitutions) fails to print
the expression correctly:
text(c(5,5),c(105,100),labels=c(substitute(i^{z+phantom()}*"("*a*"
AMU)",list(i="yx",z=2,a=0)),"Three"))
This is a bug, no?
Joh
