Pull data from multiple surveys with just one function call

[kellijohnson-NOAA]

In the future we should add the ability to query multiple surveys with one pull, e.g., SurveyName = c("Triennial", "AFSC.Slope")? https://github.com/nwfsc-assess/nwfscSurvey/blob/b3e36334d1b390e6020614076101f9122a52f70c/R/PullBio.fn.R#L9
Looks like it would require some restructuring of the if statements to something like

if (any(SurveyName == "Triennial")) {

allowing multiple if statements to be true and the data to be filtered for each survey.
Some additional data merging would be needed as well.

I agree. I initially constructed the code to pull only a single survey at a time in order to prevent people from accidentally combining data across surveys when creating indices or composition data for assessment. I think with some careful thought, the code can be reworked in order to not only pull multiple surveys, but also have traps to ensure proper processing of the data. I will try to revisit this post-assessment season.

I agree. I had added a function to just pull the haul data (including environmental variables) and allowed multiple surveys to be grabbed at the same time. Surveys can be NULL, e.g.

haul_dat = PullHaul.fn()

One general thing to think about is right now, the user inputs (years, surveys, species, variables) are used to write a text string for the JSON query. Another option would be to grab all the data initially, and then apply filtering (using dplyr or whatever).

I'm happy to help with the other functions after the assessment season is wrapped up.
