r - 我想要一个用于列出布局的单选按钮(径向、对角线网络和 dendroNetwork)

Question

我已经编写了用于生成网络图的 UI、服务器和 global.r。它适用于一种布局(layout.fruchterman.reingold)。我想要一个用于列出布局的单选按钮(径向、对角线网络和 dendroNetwork):

Global.R file for producing the graph

###          Social Network Analysis /Word Network  ##########
###############################################################
tdm <- TermDocumentMatrix(r_stats_text_corpus,control = list(wordLenghts = c(1,Inf)))
idx <- which(dimnames(tdm)$Terms == "call")  ##change the terms to be searched 
tdm2 <- removeSparseTerms(tdm, sparse = 0.994)
m2 <- as.matrix(tdm2)
m2[m2>=1] <- 1
m2 <- m2 %*% t(m2)  ##Adjaceny Matrix
g <- graph.adjacency(m2, weighted=T, mode = "undirected")
g <- simplify(g)
V(g)$label <- V(g)$name
V(g)$degree <- degree(g)
set.seed(3952)

layout1 <- layout.fruchterman.reingold(g)

###Different Formats for Social Network Graphics

##Radial 
radial <- as.radialNetwork(fit)
radialNetwork(radial)

#Diagonal Network 
diagonalNetwork(radial, height = NULL, width = NULL, fontSize = 10,fontFamily = "serif", linkColour = "#ccc", nodeColour = "#fff",nodeStroke = "steelblue", textColour = "#111", opacity = 0.9,margin = NULL)

#Dendro Network 
dendroNetwork(fit, height = 500, width = 1000, fontSize = 10,
              linkColour = "#ccc", nodeColour = "#fff", nodeStroke = "steelblue",
              textColour = "#111", textOpacity = 0.9, textRotate = NULL,
              opacity = 0.9, margins = NULL, linkType = c("elbow", "diagonal"),
              treeOrientation = c("horizontal", "vertical"), zoom = TRUE)

Here is how my server.R looks for just the graph section  

output$sna <- renderPlot({
        plot(g, layout=layout1)

      })
And the user interface ui.r  is as below  
conditionalPanel(condition="input.tabselected==10",radioButtons("layout","Select the layout to be plotted",c("layout.fruchterman.reingold","kawai","graph_net","radialNetwork","dendroNetwork","diagonal Network")))

如何绘制所有不同的格式？此处列出了相同的数据(主要来自 YouTube Comment Scraper 的非结构化评论):

head(data1,18) 1 "Call of star wars a halos destiny"
[2] "I thought of an new call of duty name CALL OF DUTY: The road of ARK GIANT"
[3] "Activision must be destroyed for the sake of video games. Boycott those pieces of shits."
[4] "FuturisticðŸ˜"
[5] "1:09 is that the XM 53"
[6] "Lets just not..."
[7] "Petition to call next CoD \"Space Cadets: Fanny Warfare\""
[8] "This is just pathetic...."
[9] "BLEAH"
[10] "I hate treyark now for the Campaign ending"
[11] "this isn't a cod trailer"
[12] "It's actually a good game just because you don't get to stand on solid ground 24/7 doesn't mean you have to cry about it, if you don't like the game then go play something else not rage about it to Activision, and do us a favor and go back to World at War please."
[13] "AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHahahahahahahahahahah! Oh, my God, I'm sorry sorry, I, it's just.... AHAHAHAHAHAHAHAHAHAHAHAHahahahah! Canada builds wall!

[18] "Phelps?"

Answer 1

我不得不承认我发现这是一个引人入胜的话题和一个好主意。您将大部分代码放在一起 - 只需进行很少的更改，我就可以使用它。然后我优化了一点以反射(reflect)输入依赖关系 - 即添加 reactive职能。

此外，我认为您在这里并不真正想要单选按钮，您真正想要的是选项卡。所以我把它放在一起 - 添加一个也可以将它们一起显示的选项卡:
