Base `histogram` returns syntax errors

[Quan Le]

Hi all,

I'm struggling with broken calls to

histogram

. The minimum reproducible example is rather silly:

. clear

. sysuse auto
(1978 automobile data)

. twoway histogram price
invalid syntax
r(198);

. histogram price
(bin=8, start=3291, width=1576.875)
invalid syntax
r(198);

. which histogram
/Applications/Stata/ado/base/h/histogram.ado
*! version 1.3.6  03apr2025

. macro list

The Stata version is StataNow/MP 18.5 for Mac (Apple Silicon) Revision 26 Feb 2025.

I can upload

histogram.ado

but that seems to be discouraged by forum norms / it's StataCorp's IP, so I'll refrain until asked to do so.

Thanks!

You should first update Stata. If that doesn't resolve the issue, you may need to reinstall Stata from scratch. histogram is an official command that comes bundled with your Stata installation, so there should be no need to upload any separate ado files.

update all

If none of these steps work, contact Technical Services for assistance: https://www.stata.com/support/tech-support/contact/.

Thanks. Sorry that I just edited the minimum example to include the

update all

call.

Will contact tech support.

You should probably do a

set trace on

to see what exactly is throwing the error. It is not histogram.ado itself. That file actually calls graph twoway histogram. You are also separately getting an error with twoway histogram. So that's a clue that it's some program / file called by graph twoway histogram that may have been altered / corrupted.
