着迷。
编辑:解决方案
正如 MartineJ 和 emilliman5 所指出的,节点应该被唯一标记(如下)。
library("riverplot")
nodes<-structure(list(ID = c("2011+", "2011-", "2016+", "2016-"), x = c(20,
20, 30, 30), y = c(50, 40, 50, 40)), class = "data.frame", row.names = c(NA,
-4L))
edges<-structure(list(N1 = c("2011+", "2011-", "2011+", "2011-"), N2 =
c("2016+", "2016-", "2016-", "2016+"), Value = c(461, 7, 0, 46)), class =
"data.frame", row.names = c(NA, -4L))
river <- makeRiver(nodes,edges)
riverplot(river)
我一直在尝试绘制一个桑基图/河图(使用河图包)来说明癌症登记如何随着时间的推移而演变,尽管到目前为止,这段代码并没有给我带来什么成功。任何人都可以指导我这个代码的错误吗?
Warning message: In checkedges(x2$edges, names(x2)) : duplicated edge information, removing 1 edges
这是可疑代码:
library(“riverplot”)
edges<-structure(list(N1 = c("+", "-", "+", "-"), N2 = c("+", "-", "-", "+"), Value = c(664L, 50L, 0L, 46L)), .Names = c("N1", "N2", "Value"), class = "data.frame", row.names = c(NA, -4L))
nodes = data.frame(ID = unique(c(edges$N1, edges$N2)), stringsAsFactors = FALSE)
nodes$x = c(1,2)
rownames(nodes) = nodes$ID
rp <- list(nodes=nodes, edges=edges)
class(rp) <- c(class(rp), "riverplot")
plot(rp)
以及包含在代码中的数据:
N1 N2 Value
+ + 664
- - 50
+ - 0
- + 46
感激不尽。
