Error Code r(4026) rvalue invalid

[Andrea Huriega]

Hi,

I keep getting an error code return of r(4026) rvalue invalid when trying to run certain graphs and then eventually once this error code returns it won't run any graphs. I have ensured all the variables exist in their correct numerical format but I can't figure out the source of the error.
Here's the line of code that works
"graph bar arcsinsqrt_nmolcomp if dsample==14 & set==6, over(tissueid, label(angle(45))) over(AA) bar(1, color(black)) ylabel(0.0 0.1 0.2 0.3 0.4,nogrid) subtitle("E. Ring", position(11)) name(ring, replace)"
Then when I run this code, it returns r(4026) and prevents me from running other graphing code after
"graph bar arcsinsqrt_nmolcomp if dsample==14 & set==7, over(tissueid, label(angle(45))) over(AA) bar(1, color(black)) ylabel(0.0 0.1 0.2 0.3 0.4,nogrid) subtitle("F. Sulfur", position(11)) name(sulf, replace)"

That sounds quite deep. Can you show the results of

dataex arcsinsqrt_nmolcomp tissueid AA if dsample == 14 & set == 6

or of any data example that reproduces the problem.

Thanks so much for a quick response!
Here are the results from that code:

Perhaps I should be asking for the selection

if dsample==14 & set==7

[Hua Peng (StataCorp)]

Interesting, it seems running the bar command twice trigger the error, the following is a reproducible example base on the data.

exit

running either bar command alone works fine. By the way, I tested from Stata 19 back to Stata 16, and get the same error as OP.

[Hua Peng (StataCorp)]

Ok, I think I know what's going on, Andrea Huriega, please change name(ring, replace) in the command to something else, like name(g1, replace). Stata graphics system has an internal class named ring, when you use it as a graph name, it caused system confution, hence the error in the subsequent graph command.

[Andrea Huriega]

Ah perfect! That fixed the problem, thank you so much for the help!
