Troubles setting random regression effects

[rtassinari]

Dear perpdgo

I'm having a problem applying lmerUvcov() function with using some random regression effect (x1 | id), it prints that error:

#lmerUvcov(y~ rep + (x1 | ID),data=phe, Uvcov = list(ID = list(K=A)))
Factoring method for matrix K associated with ID was set to 'auto'
Computing relfac using Cholesky
Error in Tfac[[m]] %*% Ztlist[[j]] : 
  Cholmod error 'A and B inner dimensions must match' at file ../MatrixOps/cholmod_ssmult.c, line 80

Maybe you can kindly help me, thank you.

By chance, the datasets:
A.txt
pedigree.txt
pheno.txt
