使用 ggplot 循环答案

【问题标题】：Loops with ggplot使用 ggplot 循环
【发布时间】：2022-01-11 14:37:27
【问题描述】：

我想查看我的个体鱼数据中的模式。我使用本文中提供的代码在 ggplot 中为个人制作了一个工作图。在这里，我选择列名为Transmitter 的每条鱼。这意味着我必须为每个图选择发射器，这效率不高。我有 10 个唯一的发射器名称，我想在 10 个图中可视化它们，但我想循环这个，所以我不必复制粘贴所有内容。我怎样才能自动化呢？额外问题：如何在 R 中可视化 10 个图（左、右 2 个图和彼此下方 5 个），以便我可以快速扫描我的图？提前致谢！

我使用的 ggplot 代码：

library(spatialrisk)
library(ggplot2)

pattern2     <- Brpattern[Brpattern$Batch.location == "Medemblik",]
pattern2 <- points_in_circle(pattern2, lat_center = 52.76098, lon_center = 5.12172, lon = Longitude, lat = Latitude, radius = 1e6)
pattern2$distance_m <- pattern2$distance_m/1000
colnames(pattern2)[which(names(pattern2) == "distance_m")] <- "Distance (km)"

### Fish selection
patternME <- pattern2[pattern2$Transmitter == "A69-1602-59768",]
ggplot(patternME, aes(Date, `Distance (km)`))+
  geom_point(aes(colour = Location.Receiver), size=3)+
  scale_x_date(date_breaks = "months", date_labels = "%m-%Y")+
  ggtitle("Batch location Medemblik") + ylab("Distance from batch location (km)") + labs(colour ="A69-1602-59768")+
  theme(plot.title = element_text(hjust = 0.5))

【问题讨论】：

能不能把points_in_circle()这个函数加进去？
@Peter 它来自spatialrisk 包。你仍然是对的 - 好问题包括所有使用的非基础 R 库。
我编辑我的问题。应该是包spatialrisk
patternDO 在哪里定义？您能否在新的 R 实例中检查您的问题并确认它是可重现的，它可能需要 Transmitter == "A69-1602-59768" 的值。此外，最好从问题中生成您需要的 10 个绘图中的至少两个。
我删除了那行，很抱歉没有必要。我对 R 和这个社区还是新手，必须找到使用这个网站的方式。谢谢你的耐心:)！

【解决方案1】：

您可以通过Transmittersplit 数据并创建绘图列表。

library(spatialrisk)
library(ggplot2)

plot_data <- function(data, title) {
  
ggplot(data, aes(Date, `Distance (km)`))+
  geom_point(aes(colour = Location.Receiver), size=3)+
  scale_x_date(date_breaks = "months", date_labels = "%m-%Y")+
  ggtitle("Batch location Medemblik") + 
    ylab("Distance from batch location (km)") + 
    labs(colour = title)+
  theme(plot.title = element_text(hjust = 0.5))
}

list_of_plots <- purrr::imap(split(pattern2, pattern2$Transmitter), plot_data)

可以通过[[ 访问各个地块，即list_of_plots[[1]] 用于第一个地块，list_of_plots[[2]] 用于第二个地块，依此类推。

【讨论】：

这就是我想象的样子！但是，似乎每个情节都是一样的。发射器名称变化很好，但绘制的点不正确
要使其工作，您只需将patternME <- pattern2[pattern2$Transmitter == "A69-1602-59768",] 更改为patternME <- pattern2[pattern2$Transmitter == unique(pattern2$Transmitter)[x],]，然后遍历x。作为旁注，您可能想查看cowplot 库。
你是什么意思：遍历X？我还需要手动填写发射器名称来代替 x 吗？
@DJ 你能解释一下迭代x是什么意思吗？根据您的建议，我无法使其工作。
