Hello, I try to simulate an ARMA-model using R, but I didn't find any function to generate such timeseries. In Splus there is the function arima.sim which generates AR-, MA- and ARIMA-series. Is there any similar in R?

It works for univariate AR-, MA- and ARIMA-series as well as the multivariate versions sometimes called VAR, VMA, VARMA and VARIMA and also with exogenous variable, sometimes called ARX, MAX, ARMAX, ARIMAX, VARX, VMAX, VARMAX, VARIMAX. (I use ARMA to mean all these.) There is also a simulate method for state space models.
