I'm currently trying to process an MCA on a dataset of 100'572 x 52. However, I receive the message :

Error: cannot allocate vector of size 37.7 Gb

Before buying some new RAM (I've 2x8GB of RAM and I'm working on Windows 11), I wanted to try to process my MCA on the disk.

I tried the "disk.frame" package. However, when I wanted to process my MCA :

res.FAMD <- FAMD(Athle.pre.mca1, sup.var = c(50, 51, 52), graph = FALSE) Error in 1:nrow(base) : argument of length 0

Athle.pre.mca1 being a disk.frame object.

Do you guys have any solution ?

I think you need to also include the code you used to lead up to this error, otherwise its hard to tell what caused it. From the looks of things it looks like its just a massive dataset and may have issues because of that, but I'm not familiar with MCA. – Shawn Hemelstrand Nov 16 '22 at 06:55
