Running e.g.

df1 <- data.frame(r = c(1+1i, 2-1i))
df2 <- data.frame(r = c(1-1i, 2+1i))

yields "R Session aborted - R encountered a fatal error. The session was terminated."

Similar error when using summarize, group_by with complex values :

a = data.frame(r = 1i*rnorm(1000), k = sample(1:5, 1000, replace = T))
a %>% group_by(k) %>% summarise(mean(r))

crashes R with
