Rename the topics after classifying and linking

Source: R/topic_functions.R
topics_rename.Rd

Topics will be renamed in order of the input of new_names, which should be a character vector. For example, if you had topic_1 and topic_2, and you wanted to rename them 'sustainability' and 'climate_change', new_names should be input as new_names = c("sustainability", "climate_change"). This will mean that when plotting, the order is preserved. If you want to re-order the topics after renaming them, you should use `forcats::fct_reorder()` separately, or `mutate` & `factor()`

Usage

topics_rename(classified_df, k, new_names, topic_var = topic)

Arguments

classified_df

output of the `topics_classify` function

k

Value of k used to generate topic model

new_names

Desired new names in order of k

topic_var

The topic variable in your classified df

Value

Data Frame with topic variable renamed and ordered as a factor.

Examples

list_data <- SegmentR:::test_data()
#> Making DTMs
#> making tuning grid
#> setting up LDAs
probabilities <- list_data$explore$probabilities[[1]]
data <- list_data$lda$data[[1]]

linked <- topics_link(data, probabilities)
classified <- topics_classify(linked, 0.75)
topics_rename(classified, k = 3, new_names = c("Name 1", "Name 2", "Name 3"))
