# Is it possible to model continuous time series with exogenous regressors?

I've got an irregularly spaced time series with regressors. I've found the R packages cts and ctsem for continuous time series, but they don't allow for exogenous variables. Is it possible to have both features in the same model?

Subject level latent dynamic modelThe subject level dynamics are described by the stochastic diﬀerential equation:$$dη(t)=Aη(t)+b+Mχ(t)dt+GdW(t)$$ (1)
