在Rstudio中，我可以'；t将饼图保存为plotly生成的html

我在R中使用plotly来构造交互式图形。。。 但是我在rstudio中导出为html时遇到了问题（在我的pc中-在其他一些pc中没有问题）

例如，当我做这样的事情时

id<- rep(1:10) 
df<- as.data.frame(id)
df$response<- c(rep("sim", 3), rep("nao", 2), rep("sim", 1), rep("sim", 4))
tab<- as.data.frame(freq(df$response))
tab<- tab[-3,]

library(plotly)

plot_ly(tab, labels = row.names(tab), values = Percentual, type = "pie") %>%
     layout(title = enc2utf8("Sim/Nao response") )

我使用的是windows 7和Rstudio版本0.99.447–©2009-2015

我认为您需要确保字符串采用UTF-8编码。试试这个

编码（df$response），它不起作用。我编辑了一些有关编码的结果…请尝试htmlwidgets:：saveWidget？saveWidget（as.widget（p），file=“m2.html”）pandoc.exe:无法解码字节“\xf3”：Data.Text.Internal.Encoding.Fusion.streamUtf8:无效的UTF-8流错误：pandoc文档转换失败，错误为1另外：警告消息：正在运行命令'“C:/Program Files/RStudio/bin/pandoc/pandoc”+RTS-K512m-RTS C:\pnadc216\m2.html——从markdown\u strict——输出C:\pnadc216\m2.html——自包含——模板C:\Users\miguel.orrillo\AppData\Local\Temp\RtmpwDZlyv\file46705397168d.html”的状态为1
