Label Partisan Vote Shares

For example, a 45% Democratic vote share becomes "R+10" or "55% R".

Usage

label_party_margin(midpoint = 0.5, reverse = FALSE, accuracy = 1)

label_party_pct(midpoint = 0.5, reverse = FALSE, accuracy = 1)

Arguments

midpoint

Either 0.5, the default, or 0. For label_party_margin(), if zero, scale will not be doubled (0.05 becomes "D+5" with midpoint=0, while 0.55 becomes "D+10" with `midpoint=0.5)

reverse

If TRUE, reverse "D" and "R".

accuracy

As with scales::number_format

Value

A labeling function

Examples

labeler = label_party_margin(accuracy=0.1)
labeler(c(0.3, 0.5, 0.543))
#> [1] "R+40.0" "Even"   "D+8.6" 
labeler = label_party_margin(reverse=TRUE)
labeler(c(0.3, 0.5, 0.543))
#> [1] "D+40" "Even" "R+9"
