r - Merging multiple data.tables

Question

I am aware that one can merge (join) two data.table with the merge function or the [.data.table function. However, if I have say 10, data.tables and want to use do.call to merge them all together, is there a function that would do this? Currently I resort to do.call(cbind, ...) which works for only very special cases.

Answer 1

Not sure, but maybe (untested) :

Reduce(merge,list(DT1,DT2,DT3,...))
