When I do a Correspondence Analysis using R it comes an error like this picture It plot a picture when I use the same fviz_ca_biplot method and the All4 data with more columns(8 columns, cross gender and age). This time I use just gender that has only 2 columns. Why this happened just because of the different columns number? How can I solve it.enter image description here

When I return to the former situation, it remains ok. I didn't find any similar problem yet by google.

  • Greetings! Usually it is helpful to provide a minimally reproducible dataset for questions here so people can troubleshoot your problems (rather than a table or screenshot for example). One way of doing this is by using the `dput` function on the data you are using and pasting the output into your question. You can find out how to use it here: https://youtu.be/3EID3P1oisg – Shawn Hemelstrand Nov 16 '22 at 07:19
