Try this,
items <- c(list(col=2),list(pch=2))
par(mfrow=c(2, 1))
for (ii in seq(2)) {
do.call(function(x, y, ... ) plot(1:10, ...), items[ii])
}
?do.call

Dear R-users,
I would like to know if is it possible to set a function argument as
an
evaluated expression. I have tried several syntaxes, including the
following example, but could not get it anything to run. The plot
function is used here but I would like to later apply the same
approach
to other functions.

items <- c(expression(col=2),expression(pch=2))
for (in in seq(2)) {
plot(1:10, eval(items[i]))
}

Thanks in advance for your input.
