visualize warns with bad arguments

Code
  res_ <- gss_tbl %>% specify(age ~ hours) %>% hypothesize(null = "independence") %>%
    generate(reps = 100, type = "permute") %>% calculate(stat = "slope") %>%
    visualize(obs_stat = obs_slope, direction = "right")
Condition
  Warning:
  The arguments `c("obs_stat", "direction")` are deprecated in `visualize()` and will be ignored. They should now be passed to one of `shade_p_value()` or `shade_confidence_interval()`.

visualize basic tests

Code
  hours_resamp %>% visualize(bins = "yep")
Condition
  Error in `visualize()`:
  ! `bins` must be 'numeric', not 'character'.

argument "obs_stat" is missing, with no default

Code
  res_vis_theor_none_1 <- gss_tbl %>% specify(sex ~ college, success = "female") %>%
    hypothesize(null = "independence") %>% calculate(stat = "z", order = c(
    "no degree", "degree")) %>% visualize(method = "theoretical")
Message
  Rather than setting `method = "theoretical"` with a simulation-based null distribution, the preferred method for visualizing theory-based distributions with infer is now to pass the output of `assume()` as the first argument to `visualize()`.
Condition
  Warning:
  Check to make sure the conditions have been met for the theoretical method. infer currently does not check these for you.

Code
  gss_tbl %>% specify(sex ~ college, success = "female") %>% hypothesize(null = "independence") %>%

    order = c("no degree", "degree")) %>% visualize(method = "both") +
    shade_p_value(direction = "both", obs_stat = obs_diff)
Condition
  Warning:
  Check to make sure the conditions have been met for the theoretical method. infer currently does not check these for you.
  Error in `theoretical_layer()`:
  ! Your `calculate`d statistic and the theoretical distribution are on different scales. Use a standardized `stat` instead.

Code
  gss_tbl %>% specify(partyid ~ NULL) %>% hypothesize(null = "point", p = c(dem = 0.4,
    rep = 0.4, ind = 0.2)) %>% visualize(method = "traditional")
Condition
  Error in `visualize()`:
  ! Provide `method` with one of three options: `"theoretical"`, `"both"`, or `"simulation"`. `"simulation"` is the default for simulation-based null distributions, while `"theoretical"` is the only option for null distributions outputted by `assume()`.

method = "both" behaves nicely

Code
  gss_tbl %>% specify(hours ~ NULL) %>% hypothesize(null = "point", mu = 4) %>%
    generate(reps = 100, type = "bootstrap") %>% visualize(method = "both")
Condition
  Error in `visualize()`:
  ! `generate()` and `calculate()` are both required to be done prior to `visualize(method = "both")`

Code
  res_method_both <- gss_tbl %>% specify(hours ~ college) %>% hypothesize(null = "point",
    mu = 4) %>% generate(reps = 10, type = "bootstrap") %>% calculate(stat = "t",
    order = c("no degree", "degree")) %>% visualize(method = "both")
Condition
  Warning:
  With only 10 replicates, it may be difficult to see the relationship between simulation and theory.
  Warning:
  Check to make sure the conditions have been met for the theoretical method. infer currently does not check these for you.

Traditional right-tailed tests have warning if not right-tailed
