category_highlight_tokens {tokenbrowser} | R Documentation |
This is a convenience wrapper for tag_tokens() that can be used if tokens need to be colored per category
category_highlight_tokens(tokens, category, labels = NULL, alpha = 0.4, colors = NULL, span_adjacent = F)
tokens |
A character vector of tokens |
category |
A numeric vector with values representing category indices. |
labels |
A character vector with labels for the categories |
alpha |
Optionally, the alpha (transparency) can be specified, with 0 being fully transparent and 1 being fully colored. This can be a vector to specify a different alpha for each value. |

A character vector with color names for unique values of the value argument. Has to be the same length as unique(na.omit(category)) |
span_adjacent |
If TRUE, include adjacent tokens with identical attributes within the same tag |
a character vector of color-tagged tokens
tokens = c('token_1','token_2','token_3','token_4') category = c(1,1,NA,2) category_highlight_tokens(tokens, category)
