Dear R-developers,
I just realized that rank() behaves inconsistent if combining one of na.last in
{TRUE|FALSE} with a ties.method in {average|random|max|min}.
The documentation suggests that e.g. with na.last=TRUE NAs are treated like the
last (=highest) value, which obviously is not the case:
Dear list-subscriber,
in the process of writing a general code snippet to extract coefficients
in an expression (in the example below: 0.5 and -0.7), I stumbled over
the following peculiar (at least peculiar to me:-) ) sorting behaviour
of the function all.names():
expr1 - expression(x3 = 0.5 *
Hi Everyone
I have a function f which does something using a function g. Function f
is in a library and g has a default stub in the library but will be mainly
overloaded in a later R script. For example:
## In a compiled package 'P' #
g - function() {
Rewrite
expr2 - expression(x3 - 0.5 * x1 - 0.7 * x2)
like this:
expression(`-`(x3, `-`(`*`(0.5, x1), `*`(0.7, x2
and it becomes clear.
