我正在尝试使用 R 中的 networkD3 生成一个简单的力网络图,但使用以下代码没有得到任何输出或错误。 我已经确认我的节点 ID 是 0 索引,数值和名称/组字段是字符。 任何帮助,不胜感激。

library(networkD3)
zz <- "name id group source target value
A 0 A 0 1 2199
B 1 A 1 0 784
C 2 B 2 4 394
D 3 B 3 2 382
E 4 B 4 8 340
F 5 B 5 9 286
G 6 B 6 5 279
H 7 A 0 7 279
I 8 B 7 0 240
J 9 B 8 0 196
K 10 A 9 0 174"
df<- read.table(text=zz, header = TRUE)
nodes <- df %>%
select(name,id,group) %>%
mutate(name = as.character(name),id = as.numeric(id), group=as.character(group))
links <- df %>%
select(source,target,value) %>%
mutate(source = as.numeric(source),target=as.numeric(target),value=as.numeric(value))
# simple with default colours
forceNetwork(Links = links, Nodes = nodes,
Source = "source",
Target = "target",
NodeID ="name",
Group = "group",
Value = "value",
Nodesize = 1,
width = "1000px",
height = "600px",
opacity = 0.9,
zoom = TRUE)
sapply(nodes,class)
sapply(links, class)
试试这个:
forceNetwork(Links = links, Nodes = nodes,
Source = "source",
Target = "target",
NodeID ="name",
Group = "group",
Value = "value",
# Nodesize = 1,
width = "1000px",
height = "600px",
opacity = 0.9,
zoom = TRUE)
从?forceNetwork
可以看出:
大小字符串,指定节点数据中的列 具有一些值的框架来改变节点半径。参见 半径计算。
所以你是说您希望第 1 列是节点的大小,但它需要一个字符串来引用该列,即使接受位置,在节点data.frame
列 1 中不是大小而是名称。
因此,如果要确定Nodesize
请在节点中创建新列并分配所需的值。然后,将该列的名称传递给Nodesize
