set_dfm_dimnames

Internal functions to set dimnames

Description

Default dimnames() converts a zero-length character vector to NULL, leading to the improper functioning of subsetting functions. These are safer methods to set the dimnames of a dfm or fcm object.

Usage

set_dfm_dimnames(x) <- value

set_dfm_docnames(x) <- value

set_dfm_featnames(x) <- value

set_fcm_dimnames(x) <- value

set_fcm_featnames(x) <- value

Arguments

`x`	dfm or fcm
`value`	character a vector for docnames or featnames or a list of them for dimnames

Examples

dfmat <- dfm(tokens(c("a a b b c", "b b b c")))
quanteda:::set_dfm_featnames(dfmat) <- paste0("feature", 1:3)
quanteda:::set_dfm_docnames(dfmat) <- paste0("DOC", 1:2)
quanteda:::set_dfm_dimnames(dfmat) <- list(c("docA", "docB"), LETTERS[1:3])
