  • changed sep="-" to sep=" - " in separate_ call in tidy_emmeans
  • return a tibble from tidy_emmeans
  • add test data and test to test_lsmeans.R

Output looks like

suppressMessages(library(tidyverse))
suppressMessages(library(broom))
suppressMessages(library(lsmeans))
data_frame(y = rnorm(100), x = rep(c("Single", "Double-Barrelled"), 50)) %>% 
  lm(y ~ x, data = .) %>% lsmeans::lsmeans(., ~x) %>% lsmeans::contrast(., 
  "pairwise") %>% tidy %>% print()
#> # A tibble: 1 x 7
#>   level1           level2 estimate std.error    df statistic p.value
#> * <chr>            <chr>     <dbl>     <dbl> <dbl>     <dbl>   <dbl>
#> 1 Double-Barrelled Single   0.0617     0.187    98     0.329   0.743
