Hi,
If you want parametric modes you could fit mixtures with different numbers
of components and select the best model with your favourite model-selection
criterion. Various packages such as mclust and fitdistr may be helpful in
doing this, the cluster task view has many more:

I am not aware of non-parametric mode testing routines in R, which ones were
you thinking of?
