How to handle large data; 1us datasets for pca analysis

[Former user]

I'm getting an error like this:

Error in hclust(dist(pc$z[, 1:2])) : size cannot be NA nor exceed 65536

Appreciate your help in this regard. Thanks

Your data are probably too large. Reduce it by, e.g., hclust(dist(pc$z[seq(1, nrow(pc$z), 10), 1:2])). This will select one for every 10 frames (so the size is reduced by 10 times).
