Hi folks,
I am wondering if the following is possible: I want to control the
arguments sent to a function by string variables. For example,
instead of
> heatmap.2( A, col=greenred(75) )
I would want to have something like:
> heatmap.2 ( paste(A, "col=greenred(75)", sep=",") )
Is this possible to do that?
It is possible (to do various things), but that would fail. You would
need to pass a character argument to parse() and then eval() but
probably not in the argument list. And there are possibly much cleaner
ways of doing what you want to achieve. Can you describe "what you
want to achieve" in more detail? An example that presents R objects is
the accepted manner for posing such questions.
If you plan to redefine heatmap.2, it might be as simple as:
require(gplots)
heatmap.2A.rg <- function(A, col, ...) {heatmap.2(x= A,
col=greenred(75), ... )}
