Thank you very much for creating this wonderful package.

I would like to request a parameter in twoord.plot function that controls the orientation of the y-axes labels.

I have tried code examples in the documentation of twoord.plot. I found that the y-axes labels are horizontally oriented so that sometimes some strings of the labels are truncated when printed to a file. I don't know how to change the orientation through the parameters in twoord.plot function.

Recently someone in Stackoverflow (here ) also asked how to control the y-axes labels orientation, and I offered a solution by emptying the strings in ylab and rylab and then use mtext function to control the orientation.

It would be more elegant if the y-axes labels orientation can be controlled directly from twoord.plot parameters.

Thank you again for your time.
