Combine with `PEcAnRTM`

[ashiklom]

Hi! I just discovered this package from Jeannine Cavender-Bares's talk at the NASA Ecological Forecasting meeting. This is a great package -- well done! I wanted to let you know that I have been implementing some very similar ideas in my own package -- PEcAnRTM -- and I wanted to express my interest in migrating a few of the features of my package into this. A few of the key features are:

• The ability to use [[ to subset spectra objects by wavelength -- e.g. my_spec[[400:700]], my_spec[[-(1300:1400)]].
• A spectra method for cbind that combines spectra by their common wavelengths. (Eventually, I'd like to implement mathematical operations -- +, * -- that do this as well).
• Re-sampling spectra to the spectral resolutions of common sensors (e.g. AVIRIS, Landsat, MODIS) based on their spectral response curves.

That would make the focus of PEcAnRTM more precisely on radiative transfer modeling, and allow my software development related to spectra processing to not be weighed down by all the PEcAn infrstructure.

Let me know what you think! I figured we can use this issue to discuss ideas and open separate issues for specific features, etc.

We'd love to chat a more about that @ashiklom. I've been using PEcAnRTM a lot recently and it would be great to have the two packages work synergistically.

Mostly out of laziness, we haven't laid out in writing our vision or an API philosophy for spectrolab. I'm wondering if you, @annakat and I should kickstart things with a call. I'm looking forward to talking to you!

Great! I'm defending my dissertation on June 4, so perhaps we can touch base sometime after that? Also, looping @serbinsh into this conversation.

@ashiklom no rush at all. good luck!
