standardize names

[RobertMyles]

Just check to standardize the variable names in the data frames returned. If one df has party_id, for example, the same info should be party_id in all data frames, unless it's very specific to something else.

[RobertMyles]

For example, there are variables in the Senate part that are bill_number, whereas in the Chamber they are number_bill. Let's standardize them? (I'm going to suggest the Senate way :-D )

Other things should probably be standardised too:

• if we're using sen_ for the senate, wouldn't it be better to use cha_ for the chamber of deputies?
• people will probably search for bills using the type, so maybe renaming cam_bill_info_tny.R to cam_bill_info.R would be more intuitive
• if possible, merge the original cam_bill_info_tny.R into the new function, with bill id as an argument

@RobertMyles and @duarteguilherme, any ideas?

[duarteguilherme]

I'll standardize bill_number later.

What do you think about "cham" instead of "cam"? I think it's a better option

[danilofreire]

Yes, I wrote that on Facebook a few minutes ago. It could either be cha_ or cham_, although the last sounds better to me. It's easier to pronounce in English.

[RobertMyles]

cham_ looks good to me.

[danilofreire]

Great, so let's rename the functions. I can do it if you guys want me to, then update the vignettes. Is that okay?

[duarteguilherme]

Just have to update the vignettes

[danilofreire]

Closed with commit #1f9fcd1. I checked every function and updated the vignettes. The package compiles without errors on my machine.
