Read one of the example data files bundled with the package:

library(peranavolley)
x <- pv_read(pv_example_file())
summary(x)
#> Match summary:
#> Date: 2017-09-23
#> League: 2017 AVL Men's
#> Teams: Canberra Heat Men's
#>        vs
#>        UTSSU Men's
#> Result: 3-0 (25-23, 31-29, 25-15)
#> Duration: unknown

Number of serves by team:

serve_idx <- which(plays(x)$skill == "Serve")
table(plays(x)$team[serve_idx])
#> 
#> Canberra Heat Men's         UTSSU Men's 
#>                  77                  70

Attack kill rate by player, using dplyr:

library(dplyr)
plays(x) %>% dplyr::filter(skill == "Attack") %>%
  group_by(team, player_name, player_id) %>%
  dplyr::summarize(`N attacks` = n(), `Kill rate` = mean(evaluation == "Winning attack", na.rm = TRUE)) %>%
  ungroup %>%
  dplyr::arrange(desc(`Kill rate`)) %>% dplyr::select(-player_id)
