`clm()` issues a warning message about the formula

[coeusanalytics]

Hi @runehaubo,

I believe this issue is similar to the #34 which relates to a warning regarding formula length. However, this is occurring for the ordinal::clm() function instead. Another user has already raised this in #34 but the issue has since been closed.

Due to this warning, it's causing me issues with rendering tables using another package.

Can this function be fixed as well?

Thanks.

See reproducible example below:

---

# load packages
library(ordinal)
library(dplyr)

# data set
df <- mtcars %>% 
  mutate_all(.funs = ~ factor(.)) %>% 
  mutate(very_very_very_long_variable1 = cyl,
         very_very_very_long_variable2 = vs,
         very_very_very_long_variable3 = gear)

# this produces a warning
clm(formula = very_very_very_long_variable1 ~ very_very_very_long_variable2 + very_very_very_long_variable3,
    data = df)
#> Warning: Using formula(x) is deprecated when x is a character vector of length > 1.
#>   Consider formula(paste(x, collapse = " ")) instead.

# this does not result in a warning
clm(formula = cyl ~ vs + gear,
    data = df)
#> formula: cyl ~ vs + gear
#> data:    df

What is your sessionInfo()?

Try installing the GitHub version of the package- that should fix your problem.

Looks like it has. Thanks @runehaubo.
