[R] Is there any Time series change-point estimate in R?

I am currentlly investigating the package strucchange.
My interested change-point is the covariance structure change. Can strucchange do that? Does strucchange consider Box-Jenkins model?

This is both very vague. You might find a suitable test for
non-stationarity in tseries. And depending on what you mean by
changepoint, strucchange might be able to do what you want. The
function breakpoints() can estimate breakpoints in linear regression
models, which includes certain types of models for non-stationary time
