Hi all,

I am doing bootstrap on a distance matrix, in which samples have been drawn with replacement. After that I do PCA on a resulted matrix, and these 2 steps are repeated 1000 times.

pca(x) is a vector where I wanted to store all 1000 PCAs; and x is from 1 to 1000
SampleD is a new matrix after resampling;

I am getting the following error message, which I don't understand: ....
+ }

Error in eigen(cv, symmetric = TRUE) : infinite or missing values in 'x'

Should I maybe not use a vector, but matrix instead? Thanks!
