Question

我想为R中的双向网络图中的顶点标签使用不同的字体。第一列是一个人的名字，第二列是该人所隶属的组织（可能有双重隶属关系）。

这是数据示例

    mBillingClient = BillingClient.newBuilder(this).enablePendingPurchases().setListener(this).build();
    mBillingClient.startConnection(new BillingClientStateListener() {
        @Override
        public void onBillingSetupFinished(BillingResult billingResult) {
            if (billingResult.getResponseCode() == OK) {
                    final Purchase.PurchasesResult purchasesResult = mBillingClient.queryPurchases(BillingClient.SkuType.INAPP);
                    if (purchasesResult.getResponseCode() == OK) {

                        final List<Purchase> purchases = purchasesResult.getPurchasesList();

                        for (final Purchase purchase : purchases) {
                        }
                    }
            }
        }
        @Override
        public void onBillingServiceDisconnected() {
            CommonUtils.showToast(mActivity, "disconnected");
        }
    });


    mUnlockPremiumButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

                final List<String> skuList = new ArrayList<> ();
                skuList.add(getString(R.string.inapp_premium_product_id));

                final SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder()
                    .setSkusList(skuList)
                    .setType(BillingClient.SkuType.INAPP);

                mBillingClient.querySkuDetailsAsync(params.build(),
                        new SkuDetailsResponseListener() {
                            @Override
                            public void onSkuDetailsResponse(BillingResult billingResult, List<SkuDetails> skuDetailsList) {

                                for (SkuDetails skuDetails : skuDetailsList) {
                                    if (getString(R.string.inapp_premium_product_id).equals(skuDetails.getSku())) {

                                        final BillingFlowParams flowParams = BillingFlowParams.newBuilder()
                                                .setSkuDetails(skuDetails)
                                                .build();

                                        final BillingResult result = mBillingClient.launchBillingFlow(mActivity, flowParams);

                                        if (result.getResponseCode() == ITEM_ALREADY_OWNED)
                                        {
                                            CommonUtils.showToast(mActivity, getString(R.string.alert_purchased));
                                        }
                                        else if (result.getResponseCode() != OK)
                                        {
                                            //always returns a getResponseCode of -1 (service disconnected)
                                        }
                                    }
                                }
                            }
                        });
        }
    });

我为绘图中识别出的数据分配了两种字体样式（无特殊样式）。但是，发生以下错误，我不知道该如何解决：

# R version 3.5.1 (2018-07-02) -- "Feather Spray"
# igraph 1.2.4

set.seed(7)

# bipartite network data
nodes <- read.csv("example.csv", header = TRUE, sep =";")
> nodes

summary(nodes)

library(igraph)

# different fonts and node shapes
shape <- c("circle", "square")
let <- c("Times", "Helvetica")

# creating graph (g)
g <- graph.data.frame(nodes, directed = FALSE)

# creating bipartite network
V(g)$type <- FALSE
V(g)$type[V(g)$name %in% nodes[, 1]] <- TRUE


plot(g, layout= layout_with_kk,
     vertex.shape= shape[as.numeric(V(g)$type) + 1],
     vertex.label.family= let[as.numeric(V(g)$type)+1]
)

我在这里找不到任何相关问题。
谢谢您的帮助和建议！

Answer 1

如果我只是运行您的代码，则会收到类似的错误消息，但是您可以通过在plot语句之前包含这些语句来解决此问题。

windowsFonts("Times" = windowsFont("Times"))
windowsFonts("Helvetica" = windowsFont("Helvetica"))

当我包含这些语句时，没有收到错误消息，并且不同的节点类型以不同的字体显示。

在双向网络图中为顶点标签使用不同的字体（Rstudio）
