Re: [R] scalable delimiters in plotmath
Thanks everyone. I've also had a look at plotmath.c where bgroup is
defined for [, {, (, . but not . It seems quite trivial to
add it, at first sight, however there is a part that I don't
understand in the RenderDelim routine,
static BBOX RenderDelim(int which, double dist, int draw, mathContext *mc,
pGEcontext gc, pGEDevDesc dd)
{
// [... snipped ...]
case '(':
top = 230; ext = 231; bot = 232; mid = 0;
break;
case ')':
top = 246; ext = 247; bot = 248; mid = 0;
break;
These integer codes make no sense to me, I have no clue which ones I
should use for and . As far as I understand these codes might
correspond to extended ascii characters whose boundaries and positions
we want to borrow. Then again, maybe it's something else entirely.
Any hints?
Best wishes,
baptiste

It's a matter of taste, but I would use \341 and \361.
However, these are still not scalable, AFAICS.
Not exactly scalable angles, but you can fake it:
plot(1, 1, main = expression(symbol(\341)~scriptstyle( atop(x,y)
)~symbol(\361)), cex.main=3)
scriptstyle shrinks the inner atop() material, and since I tested on a Mac
it should work for Baptiste.

Re: [R] scalable delimiters in plotmath
I see, thanks. Looking at this table I guess the short answer is no,
these cannot be made to scale and the only ones that could have
already been implemented in bgroup().

Hello Paul;
Both Baptiste and I have looked at the plotmath.c code and it appears
that only a few of those delimiters are supported. We specifically
have tried to use the angle brackets:
plot(1,1,
xlab=expression(bgroup(symbol(0xe1),atop(x,y),symbol(0xf1
Error in bgroup(symbol(225), atop(x, y), symbol(241)) :
invalid group delimiter
The supported delimiters appear to each be built up from three parts
that are then assembled within a bounding box and as far as I can
determine are limited to |, ||, [, {, (, ), },and }. I
needed to download the full source to find a copy, but I'm fairly sure
a guRu of your standing needs no help finding the code that handles
the bgroup display inside plotmath.c. I am not at my machine where I
was looking at it, but the code that I just found in expanded form on
the Internet bore your name as a copyright holder.
So I guess my feature request would be:
---add option for using scalable single character delimiters such as
Symbol(0xe1) and Symbol(0xe1).
I'm guessing that the reason three-component delimiters were chosen is
that it was easier to expand the middle section while not expanding
the ends as much but that's just the guess of someone who is perusing
without really being able to fully grasp the intricacies of what is
being done.

symbol(\370) ) ) # lower 1/3 of right paren
(caveat: Maybe not standard glyph-names.)
I added octal annotation to the TestChars(font=5) call that the
points help
page offers:
TestChars(font=5)
for(j in 1:14) {
for(i in 0:16){
text(i+0.2, j+.6, labels=as.octmode(i+(j+1)*16), cex=.5)}}
I do not see a trio or pair of glyphs that would form an angle
bracket.

As far as I understand these codes might
correspond to extended ascii characters whose boundaries and
positions
we want to borrow. Then again, maybe it's something else entirely.
Any hints?
Best wishes,

Hi Baptiste,
You need to use the symbol(\nnn) concept, where nnn denotes

It's a matter of taste, but I would use \341 and \361.
However, these are still not scalable, AFAICS.
Not exactly scalable angles, but you can fake it:
plot(1, 1, main = expression(symbol(\341)~scriptstyle( atop(x,y)
)~symbol(\361)), cex.main=3)
scriptstyle shrinks the inner atop() material, and since I
tested on a
Mac
it should work for Baptiste.
