Hi everyone,

I am doing PCA with labdsv package. I was trying to create a biplot graphs
in order to observe arrows related to my variables. However when I run the
script for this graph, the console just keep saying:

*Error in nrow(y) : element 1 is empty;
   the part of the args list of 'dim' being evaluated was:
   (x)*

could please someone tell me what this means? what i am doing wrong? I will
really appreciate any suggestions and help.

Thanks,

Dilys
