Hi,
I was carrying out multiple PCA analysis and out of no where it stopped working (error shown below kept popping up). I checked and the working directory is correct. So is the file name and scaling type. Does anyone know how to fix this?

explore.data(file = "norm.csv", scaling = "auto")
Error in tutticolors[k[i, ], ] : subscript out of bounds
