Basic Examples (3)

Take 'n' Monomers from the front of a sequence:

Take 'n' Monomers from the back of a sequence:

Take 'n' though 'm' Monomers of a sequence:

Additional Examples (2)

Works on explicitly typed sequences:

Works with numeric sequences as well:

ExplicitlyTyped (4)

Setting ExplicitlyTyped to True will ensure that the output is typed:

Setting ExplicitlyTyped to False will ensure that the output is not typed:

Setting ExplicitlyTyped to Automatic will type the output if the input is typed:

Setting ExplicitlyTyped to Automatic will type the output if the input is typed:

If input multiple sequences and indices but their lengths don't match, a message will throw:

Possible Issues (1)

When ExplicitTyping is removed from numeric sequences, the degenerate monomer is used:
