我有以下数据集:
## 'data.frame': 2 obs. of 3 variables:
## $ Var1 : Factor w/ 2 levels "correct","incorrect": 1 2
## $ Freq : num 84 16
## $ text_bars: chr "84%" "16%"
然后我创建一个ggplot对象。
z <- ggplot(results_graph, aes(Var1, Freq)) +
geom_bar(position="dodge",stat="identity", fill = "deepskyblue4") +
#coord_flip() +
theme(legend.title=element_blank()) +
ggtitle(expression(atop(bold("Percent of correct vs. incorrect numbers"),
atop(italic("test_test"), ""))))
此图表运行正常。如果我试试这个
ggplotly(z)
我收到以下错误:
Error in unique.default(proposed[[attr]]): unimplemented type 'expression' in 'HashTablesetup' Calls: <Anonymous> ... verify)attr -> structure -> uniaue -> uniaue.default In addition: Warning message: In instance$preRenderHook(instance): It seems your data is too big for client-side DataTables.
有什么问题可能是什么问题?
