Can I run Rstudio Server on OSX 10.13 (High Sierra). If so, can someone
please point me to install directions? I found an old post that talks about
using homebrew but I can't find the rstudio-server brew to install.

How can I print the definition of a function that is in the base
package?
for example, if I type:
which.min
I get
function (x)
.Internal(which.min(x))
environment: namespace:base
How can I see the definition of this function?
Thanks.

So functions in the base package are all written in C?
Thanks.

I was wondering why the following doesn't work:
a=c(1,2)
names(a)=c(one,two)
a
one two
1 2
names(a[2])
[1] two
names(a[2])=too
names(a)
[1] one two
a
one two
1 2
I must not be understanding some basic concept here.
Why doesn't the 2nd name change to too?
also unrelated: if I
If I assign a variable in a function, as in:
test=function(){
assign(a,c(1,2,3),env=.GlobalEnv)
}
How can I do the equivalent of:
names(a)=c(one,two,three)
within the function?
Merely adding the call to names does not work within the function as
it only affects a local variable:
is that?
Thanks.

In my experience output is not buffered on a Mac.
Are you actually *printing* out the results you want to see?
Could you, as the posting guide requests

I'm sure there is a more general way to ask this question but how do
you use the elements of a character vector as names of objects in an
expression?
For example, say you have:
a = c(1,3,5,7)
b = c(2,4,6,8)
n=c(a,b)
and you want to use the names a and b in a function (e.g. sum)
is
that n is an arbitrary length vector and I'd like to find a way that
avoids having to enumerate the elements of the character vector.
Thanks,
Ira
