How to add count labels to statebin map?
问题
以下代码创建了一个 statbin 热图。我们如何在每个 bin 上添加包含计数的标签？（所需标签已经准备在数据的 lab 列中。）
library(statebins)dat = data.frame(state = state.abb, val = rep(0:24, 2))dat$lab = paste(dat$state, dat$val, sep = "\n")head(dat)# state val lab# 1 AL 0 AL\n0# 2 AK 1 AK\n1# 3 AZ 2 AZ\n2# 4 AR 3 AR\n3# 5 CA 4 CA\n4# 6 CO 5 CO\n5sb = statebins(dat, state_col = "state", value_col = "val") +theme_statebins()sb
英文:
The following code creates a statbin heatmap. How can we add labels with the counts to each bin? (Desired labels have been prepared in the lab column of the data.)
library(statebins)dat = data.frame(state = state.abb, val = rep(0:24, 2))dat$lab = paste(dat$state, dat$val, sep = "\n")head(dat)# state val lab# 1 AL 0 AL\n0# 2 AK 1 AK\n1# 3 AZ 2 AZ\n2# 4 AR 3 AR\n3# 5 CA 4 CA\n4# 6 CO 5 CO\n5sb = statebins(dat, state_col = "state", value_col = "val") +theme_statebins()sb

我们可以直接像这样编辑构建好的绘图中的geom_text标签，确保与正确的顺序匹配：
library(ggplot2)sb = ggplot_build(sb)sb$data[[2]]$label = dat$lab[match(sb$data[[2]]$label, dat$state)]sb = ggplot_gtable(sb)plot(sb)
英文:
We can edit the geom_text label in the built plot directly like this, making sure to match the labels in the correct order:
library(ggplot2)sb = ggplot_build(sb)sb$data[[2]]$label = dat$lab[match(sb$data[[2]]$label, dat$state)]sb = ggplot_gtable(sb)plot(sb)
