Hello!

Recently, when using harmony in my new server, error occured with the messages saying that

error: element-wise pow(): incompatible matrix dimensions: 100x2 and
2x1

In the end, I fixed this issue by re-install Rcpp, changing the version from 1.11 to 1.07. See my reference here [ref]

Of note, to install a older version of Rcpp, I download the Rcpp 1.07 tar.bz2 and use conda to install the local package directly.
HTH.
