如何繪製R中的條形圖並使用特定節點的特定屬性? 我有一個GML文件是這樣的:如何在R中繪製節點屬性的條形圖
graph [
node [
id 0
label "Apple"
year 1997
bold 1
normal 4
light 15
]
node [
id 1
label "Apple"
year 2000
bold 2
normal 16
light 2
]
node [
id 2
label "BBC"
year 2010
bold 18
normal 2
light 0
]
]
和我運行該R腳本,我有麻煩時,我需要提取從一個節點選擇的屬性值:
install.packages(c("igraph"))
library(igraph)
g = read.graph(file = "/media/Data/TEMP/R_test/test.gml", format = "gml")
apple = V(g)$label[V(g)$label == "Apple"]
table(apple)
for(i in seq(along=apple)){
mL = apple[,i]$bold
L = apple[,i]$normal
pL = apple[,i]$light
barplot(????)
}
我怎麼能解決這個問題?腳本THX
THX,我怎麼能設置數據繪製一個** Stacked Bar **,就像每年在同一列中的屬性[粗體,正常,輕]一樣?我需要創建一個表格? – goodguyAbaddon
例如'df < - subset(as_data_frame(g,「vertices」),label ==「Apple」,c(year,bold,normal,light)); barplot(as.matrix(t(df [,-1])),names.arg = df $ year,main =「Apple」)'。 – lukeA
