How to create a subscript of the infinity symbol?

AliceCheng — Sat, 01 May 2021 06:00:39 GMT

When doing PK studies, once time we have the PK parameter AUC (0-inf). If I want to put '0-inf' in subscript after 'AUC' . What code should I use?

If '$' is the escapechar, I understand that ${sub 0-inf} will put '0-inf' in subscript. By searching, I found that ${Unicode 221E} will give you the infinity symbol. But how can I get the infinity symbol in subscript? What is the correct code to achieve that?

Thank you!

Hello,

Just curious: what do you mean with PK. Is it PharmacoKinetics?

To answer your question, here's an example:

options nodate nonumber;
ods html close;
ods escapechar="^";
ods rtf file="rtfInlinFuncs.rtf";

title "Example of SUB, SIGMA ^{unicode 221E} Function";
proc print data=sashelp.class(obs=4);
run;
ods _all_ close;
/* end of program */

But maybe you want the infinity symbol in the body of a report or in a graph / plot. That may complicate things.

If so, please provide the community with your trial code and things will be corrected where needed.

Cheers,

Koen

I am sorry, I forgot to use the SUB function that can be used with ODS ESCAPECHAR.

Here is better code:

options nodate nonumber;
ods html close;
ods escapechar="^";
ods rtf file="rtfInlinFuncs.rtf";

title "Example of SUB, SIGMA ^{sub ^{unicode 221E}} Function";
proc print data=sashelp.class(obs=4);
run;
ods _all_ close;
/* end of program */

ods escapechar='^';
title "Example of SUB, SIGMA^{sub 0-^{unicode 221E}}  Function";
proc print data=sashelp.class(obs=4);
run;

Thank you all for your reply. I will try this out next time when I get to my computer.

I recall I have done something similar! I will test in out and let you know the result.

But I do recall since I have other text in front of the infinity symbol, my infinity symbol

is small than the regular characters. Is there somehow I can control its size?

Any interesting result while I was experimenting. I ended up copying the infinity symbol I got from

an PDF output into my SAS program. Guess what my new pdf output has for infinity symbol? It turns 90 degree so that it became the number 8!

"my infinity symbol

Yes. You are right ,try this to adjust font size .

ods escapechar='^';
title "Example of SUB, SIGMA^{sub 0 -^{style [fontsize=4] ^{unicode 221E}}}  Function";
proc print data=sashelp.class(obs=4);
run;

Hi, KSharp,

Thank you very much for your answer.

I adjusted the code a bit. Here is what I end up using.

iPARAML='AUC${sub ${style [fontsize=0.8]0}${style [fontsize=1.0]-}${style [fontsize=1.0] ${unicode 221E}}}';

And my output looks like this.

Is there some way I can adjust so that the subscript goes lower?

This works fine in PDF and HTML, but I can hardly see any subscript by this method in RTF.

Thank you very much for your response. I really appreciated. If you have additional suggestion, please do reply!

Alice
