[R] c() question

[Simon Fear]

Christoph, yes there IS a way, such as the horrible

eval(parse(text=paste("c(", my.group[1],
  " = ", class.weight[2], ",", my.group[2], " = ", class.weight[1], ")", sep="")))

BUT I would suggest you rethink whether there isn't a an altogether
more straightforward way to do what you want. For example, 

tmp <- class.weight
names(tmp) <- my.group
