Plot of loadings reversed #32

Closed ameyenn closed 4 years ago

ameyenn commented 4 years ago

Hi,

Just teaching myself PCA and plots and loadings, categorical data, seems to work ok and will move onto look at MCA. Data set of repeat arrests, just as a learning set for me, found it difficult to get fully discrete data sets.

The plots are reversed but the same, although the x-y dim % are different.

The scree plots are similar but again % varies a little.

Any clues or suggestions, thanks for the nice package and now I know what shiny acctually does!

Could you tell me what function you used to compute the PCA ? And is the dataset available somewhere, in a package maybe ?

Thanks for taking the time to report the problem.

Hi Julien,

Problem solved, I was using a scales matrix when I used the data frame for both, all good!

Thanks
