expecting to support supplymentary category ellipses on individual plot

[419kfj]

Thank you for your support of the Supplementary variable/individual of GDAtools objects.

I use it on 0.3.8 and found that there is no function to overlay the concentration ellipses on the individual cloud.

I am expecting that "explor" will support this function.

regards.

Hi,

Concentration ellipses should work in individual plots from speMCA results. You have to choose a variable to color points with, and then check the "Ellipses" checkbox.

It doesn't work for you ? Did you try with the development version ?

juba, thank you for your quick reply.

I am using 0.3.9 and I tried to choose a variable but, there is no supplementary category.

The labels are only, "None", "Type", "TV, "Film", "Art", "Eat". (I got the Taste_example data from Prof. Le Roux's Web site, and am reading "Multiple Correspondence Analysis"SAGE, 2010)

Of course I can confirm that there are "Supplementary variables to display" check boxes in the left block and they are displayed in the variable plot.

How can I get the development version?

Oh, you meant that the supplementary variables are not displayed in the drop down menu to color points. Sorry I didn't understand at first, and you're right, I can reproduce the issue and I'll take a look into it.

To install the development version you can do the following, but for now the problem is not fixed yet.

install.packages("remotes")  # If necessary
remotes::install_github("juba/explor")

Julien,

Thank you for your reply.

OK, I will wait for the fix the issue ;-)

Best wishes

Ok, I think this should now be fixed in the development version. Don't hesitate to let me know if the issue is still present.

Julien,

I downloaded the development version. Then I check the documentation of this package, and I find the title "Documentation for package ‘explor’ version 0.3.9.9000", so it is the development version.

But the result is the same. I can't find a supplementary category on the individual plot panel, (As I wrote the previous message, I can confirm them at the Variable plot panel.)

I attached the data object which is constructed as follows.

res.speMCA$supv <- varsup(res.speMCA, .d_a$Age) # Add the Age as the supplementary variable to main result, res.speMCA, and save it as res.speMCA.rda. save(res.speMCA,file = "res.speMCA.rda") explor::explor(res.speMCA) # I tried it.

regards.

This is individual plot panel. [image: image.png]

This is Variable plot panel.

I know it is not very intuitive, but for supplementary variables you must not use GDAtools::varsup but explor::speMCA_varsup, as explained in the introduction vignette.

So in your case your code should be :

res.speMCA$supv <- speMCA_varsup(res.speMCA, .d_a$Age) 

[419kfj]

Oh! Embarrassing!

speMCA_varsup is explor::speMCA_varsup. I thought it was from GDAtools function。

I tried again。 It worked！

Thank you!

Does it work with 0.3.9?

No, it only works on the development version for the moment. It will work on the next CRAN version, but I don't know when it will be published.

[419kfj]

I see, thank you for your support!

I will share this information with my research colleagues.

best wishes.
