Weird interaction with lots of previous equations when generating PDF - flextable "fails" #636
Comments
|
I tried removing equations in turn, and it fails with a particular equation (as seen in the revised MWE). This equation tried to render a subscript symbol (theta). |
|
And the "winner" is a simple equation of The error must be caused when the font for "exp" conflicts somehow with the font specification used by flextable if flextable calls occurs after this. Again, if I put a call to flextable before the equation by changing the include: false to include: true , everything works out fine Very odd. Carl. |

Just adding a comment to confirm that I experienced this with the \ln tex command when rendering to pdf. Equations without this work fine, but running a document with flextables as well as equations with \ln fail with a similar error message to the above. |
I experience the same problem. My document compiles without issues when I remove the equations but fails as soon as I introduce them. |

I suspect that it will fail any time you use a "function" in latex such as
sin, cos etc that uses the roman font when typesetting...

@cschwarz-stat-sfu-ca My knowledge of latex is not great, do you have any idea of what to do to solve this problem? |

Sorry, but this is above my pay-grade.
From what I understand, math fonts are treated differently in latex than
other fonts and this may the root of the issue. However, that is just a
guess.
About all I can suggest is to construct a small .tex file that crashes and
try submitting to the tex stackexchange groups for advice.

Very strange issue that appears to be flextable related.
I have a quarto document (included at end). Compiles fine into HTML.
When I try and compile into PDF, I get a LateX error:

This comes from the final flextable call.
If I reduce the number of previous equations, it eventually compiles.
If I run the same chunk BEFORE the equations (e.g. change the third chunk include: to true in the MWE), then it compiles just fine as well.
