SUMMARY
When changing the class of an object that's currently opened in RKWards object
viewer, RKWARD crashes. I have attached a script that forces the crash.

STEPS TO REPRODUCE
1. Run:

library(likert)
library(dplyr)

df <- data.frame(x = c("A lot", "Some", "Not at all"))
df <- mutate(mydata, x_recoded = recode(x, "A lot" = 1, "Some" = 2, "Not at
all" = 3))

2. Open df in RKWards viewer

3. Run "df <- likert(df)

OBSERVED RESULT
RKWard crashes

EXPECTED RESULT
RKWards either closes the viewer or reloads the object
