12 Tabellen
Er zijn een aantal mogelijke manieren om een data.frame in tabelvorm weer te geven.
# functies om tabellen te genereren
cijfer_tabel <- function(rijen = 20, kolommen = 10) {
data.frame(
matrix(
rnorm(rijen * kolommen),
nrow = rijen,
ncol = kolommen
),
row.names = paste("rij", seq_len(rijen))
)
}
random_woord <- function(n_letters = 5){
paste(
sample(letters, size = n_letters, replace = TRUE),
collapse = ""
)
}
random_zin <- function(n_woorden = 10, n_letters = 10){
paste(
sapply(
rpois(n_woorden, n_letters),
FUN = random_woord
),
collapse = " "
)
}
tekst_tabel <- function(rijen = 20, kolommen = 10, n_woorden = 10, n_letters = 5){
x <- data.frame(
matrix(
sapply(
rpois(rijen * kolommen, lambda = n_woorden),
random_zin,
n_letters
),
nrow = rijen,
ncol = kolommen
)
)
colnames(x) <- head(LETTERS, kolommen)
return(x)
}
genereer_tabel <- function(rijen = 20, kolommen = c(5, 5), n_woorden = 10, n_letters = 5){
cbind(
cijfer_tabel(rijen = rijen, kolommen = kolommen[1]),
tekst_tabel(
rijen = rijen, kolommen = kolommen[2], n_woorden = n_woorden, n_letters = n_letters
)
)
}12.1 kable()
We raden aan om in eerste instantie kable() te gebruiken. De standaard (tabel 12.1) genereert zowel tabellen in pdf als HTML output formaat. In pdf formaat wordt het een floating tabel. Dat houdt in dat de volledige tabel op een pagina geplaatst wordt van zodra er plaats is om de volledige tabel te plaatsen. Is de tabel zo groot dat ze niet op een pagina past, dan valt het laatste stuk van de pagina.

Het markdown formaat is handig voor grotere tabellen met tekst. Wanneer de tekst te lang is worden de rijen over meerdere regels gespreid. Indien nodig wordt de tabel over meerdere pagina’s gespreid. Het nadeel is dat je geen bijschrift kan plaatsen en er ook niet naar kan verwijzen.

12.2 Mogelijke alternatieven
12.2.1 Aangepaste kable() formaten voor pdf output
De booktabs past een lay-out met minder lijnen toe (tabel 12.3). Nu geven we ook het gewenste aantal decimalen voor elke kolom weer. Nu past de tabel omdat we een aangepast aantal rijen en kolommen hebben gekozen.
De argumenten hebben geen invloed over het uitzicht in de HTML versie.

Het longtable formaat is geschikt wanneer we een tabel hebben die langer is dan op een pagina past (tabel 12.4). Dit soort tabel is geen floating table. Dat wil zeggen dat ze onmiddellijk start daar waar de code ze genereert. Onderaan de pagina wordt de tabel afgebroken en op de volgende pagina opnieuw gestart. Merk op dat een te brede tabel nog steeds wordt afgebroken.
kable(
genereer_tabel(40, c(4, 1), 4, 4),
digits = 2,
caption = "Longtable output van `kable()`.",
longtable = TRUE

12.2.2 Het kableExtra package
kableExtra biedt de mogelijkheid om het uitzicht van kable() tabellen aan te passen. Je kan in een zelfde commando zowel het HTML als pdf formaat aanpassen. In plaats van hier een beperkt aantal voorbeelden te geven, verwijzen we liever naar de uitgebreide vignettes van kableExtra. Ze hebben een vignette voor HTML output en pdf output.
12.2.3 pandoc.table()
pandoc.table() komt uit het pander package.
Voordelen:
- Zet tabellen steeds naar markdown formaat. Dit betekent dat je steeds een brede waaier aan outputformaten kan gebruiken.
Nadelen:
- Je moet steeds
results='asis'toevoegen aan de chunk opties.
12.2.4 xtable()
xtable() komt uit het xtable package.
Voordelen:
- Biedt veel mogelijkheden om tabellen te fine-tunen. Zie
?xtableen?print.xtablevoor alle details. Een paar handige opties:- tabellen in landscape weergeven
- rijnames of kolomnamen roteren
- het lettertype van de tabel verkleinen (of vergroten)
- Biedt native code voor latex (pdf) en HTML.
Nadelen:
- Je moet steeds
results='asis'toevoegen aan de chunk opties. - Kan niet dynamisch kiezen tussen pdf of HTML. Minder handig als je zowel HTML als pdf output wilt.
- Kruisverwijzingen zijn lastig, zeker als je ze zowel in pdf als HTML wilt hebben.
