小编Str*_*ing的帖子

我在R Riverplot中制作了一个Sankey图(v0.5),在RStudio中输出看起来很小,但是当导出或放大时,颜色有黑色轮廓或网格线.

我想这可能是因为形状的轮廓与我想用于填充的透明度不匹配？

我可能需要找到一种方法来完全摆脱轮廓(而不是让它们半透明),因为我认为它们也是为什么值为零的流仍然显示为细线的原因.

我的代码在这里:

#loading packages
library(readr)
library("riverplot", lib.loc="C:/Program Files/R/R-3.3.2/library")
library(RColorBrewer)

#loaing data
Cambs_flows <- read_csv("~/RProjects/Cambs_flows4.csv")

#defining the edges
edges = rep(Cambs_flows, col.names = c("N1","N2","Value"))
edges    <- data.frame(edges)
edges$ID <- 1:25

#defining the nodes
nodes <- data.frame(ID = c("Cambridge","S Cambs","Rest of E","Rest of UK","Abroad","to Cambridge","to S Cambs","to Rest of E","to Rest of UK","to Abroad"))
nodes$x = c(1,1,1,1,1,2,2,2,2,2)
nodes$y = c(1,2,3,4,5,1,2,3,4,5)

#picking colours
palette = paste0(brewer.pal(5, "Set1"), "90")

#plot styles
styles = lapply(nodes$y, function(n) {
  list(col = palette[n], lty = …
