Details

Objects derived from the textstat class can be indexed with simple square brackets ("[") to get rows specified by an numeric/integer vector, and with double square brackets ("[[") to get specific columns from the data.table in the slot stat.

textstat objects can have a name, which can be retrieved, and set using the name-method and name<-, respectively.

Examples

# NOT RUN {
use("polmineR")
P <- partition("GERMAPARLMINI", date = ".*", p_attribute = "word", regex = TRUE)
y <- cooccurrences(P, query = "Arbeit")
y[1:25]
y[,c("word", "ll")]
y[1:25, "word"]
y[1:25][["word"]]
y[which(y[["word"]] %in% c("Arbeit", "Sozial"))]
y[ y[["word"]] %in% c("Arbeit", "Sozial") ]
# }
