R 4.2.1
OS X

Colleagues

I am using XOJO (formerly known as RealBasic) to create a GUI -- R code 
generates the text that appears in the GUI.

Recently, VT-100 terminal control escape sequences appeared in the text, e.g.,:
         [?25h  TEXT
    [?25h[?25h  TEXT
It is not clear to me if the problem is generated by R or by XOJO.  And I did 
not track whether this began following installation of a new version of R or of 
XOJO (with no changes in the underlying code for either).

Of note, when I run the R code in a terminal in OS X, those errant characters 
do not appear.

I would like the 
        [?25h
text to disappear.  

If the problem originates in XOJO, I assume that there is nothing that can be 
done in R to solve the problem.  But, if there is something that can be done in 
my R code, it would be useful to know about it.
