Hi, R-help,
(sessionInfo at the end)
I'm trying to construct a function using bquote and running into a
strange error message. As an example, what I would like to do is this:
z <- 2
eval(bquote(function(x, y) { x^.(z) + y }))(2, 3)
However, I get the following:
Error in eval(expr, envir, enclos) :
invalid formal argument list for "function"
However, if I change the command to following, it works:
z <- 2
eval(bquote(function(x) { x^.(z) }))(2)
# [1] 4
In other words, I remove the second argument. Is there a workaround for
this without using eval(parse(text = ))?
Thanks,
--sundar
