When using c++17 with rstan 2.21 & StanHeaders 2.26 we run into the same ambiguity errors with the
size()
function - because the olderstanc
is emittingsize()
without the math qualifier. We can workaround this by using the "old" size function with rstan 2.21, which has less general templating and doesn't result in the same ambiguity errorsEDIT: This will be needed for the
blavaan
package
