R单张图例:指定顺序，而不是按字母顺序

问题描述

我在r传单代码中添加了图例，输出是这个

I added legend to r leaflet code and output is this

我想下订单

• 绿色超过66％"
• 橙色介于33％和66％之间"
• 红色少于33％"

sep <- read.csv("31R_SEP_assets_csv - Copy.csv")

Sub1 <- sep[grep("SEP.12", names(sep))]
sep$newCol <- 100*rowSums(Sub1)/rowSums(sep[4:7])

# create a new grouping variable
Percent_SEP12_Assets <- ifelse(sep[,8] <= 33, "Less than 33%", ifelse(sep[,8] >= 66, "More than 66%", "Between 33% and 66%"))

Color_Assets <- colorFactor(c("darkgreen","darkorange","darkred"),
                               levels = Percent_SEP12_Assets,ordered=FALSE)

leaflet(data = sep[]) %>%
  setView(lng = mean(sep$Longitude), lat = mean(sep$Latitude), zoom = 12) %>% addTiles()  %>%
  addCircleMarkers(~Longitude, ~Latitude,  color = ~Color_Assets(Percent_SEP12_Assets),  popup = ~as.character(paste(Site, Percent_SEP12_Assets , sep=", "))) %>%
  addLegend("bottomright", pal = Color_Assets, values = Percent_SEP12_Assets, title = "SEP 12 Installs")

dput(sep)

structure(list(Site = structure(1:5, .Label = c("Staten Island\\31R001",
"Staten Island\\31R002", "Staten Island\\31R003", "Staten Island\\31R004",
"Staten Island\\31R005"), class = "factor"), Latitude = c(40.508874,

174L, 11L, 85L, 163L), Mac.SEP.11 = c(0L, 1L, 4L, 0L, 0L), Windows.SEP.12 = c(124L,

)), .Names = c("Site", "Latitude", "Longitude", "Windows.SEP.11",
"Mac.SEP.11", "Windows.SEP.12", "Mac.SEP.12", "newCol"), row.names = c(NA,
-5L), class = "data.frame")

谢谢！

推荐答案

# create a new grouping variable
Percent_SEP12_Assets <- factor((sep[,8] > 33) + (sep[, 8] >= 66), labels = c("Less than 33%", "Between 33% and 66%", "More than 66%"))

Color_Assets <- colorFactor(c("darkred","darkorange","darkgreen"),
                           levels = Percent_SEP12_Assets,ordered=FALSE)

需要订购的因子.我还用逻辑表达式的总和替换了ifelse.

Factor with order required. I've also replaced the ifelse with a sum of logical expressions.
