Rstudio -Error: Client error: (401) Unauthorized No such user, can't open files.credentials, ./config etc

Question

当我运行 Rstudio 中的 R 代码时，出现以下错误。怎么了？'

Error: Client error: (401) Unauthorized     No such user In addition: Warning messages: 1: In open.connection(con, "rb") :   cannot open file '/Users/i073341/.plotly/.credentials': No such file or directory 2: In open.connection(con, "rb") :   cannot open file '/Users/i073341/.plotly/.config': No such file or directory 3: You need a plotly username. See help(signup, package = 'plotly')  4: Couldn't find username  5: In open.connection(con, "rb") :   cannot open file '/Users/i073341/.plotly/.credentials': No such file or directory 6: In open.connection(con, "rb") :   cannot open file '/Users/i073341/.plotly/.config': No such file or directory 7: You need an api_key. See help(signup, package = 'plotly')  8: Couldn't find api_key

R代码：

library("plotly")
a = read.csv('/Users/i073341/Library/CloudStorage/OneDrive-SAPSE/Data Analysis/result/Opportunity/20220207-151923/cleanSankey.csv', header=TRUE, sep=',')
node_names <- unique(c(as.character(a$source), as.character(a$target)))
nodes <- data.frame(name = node_names)
links <- data.frame(source = match(a$source, node_names) - 1,
                    target = match(a$target, node_names) - 1,
                    value = a$value)



#Plot
p <- plot_ly(type='sankey',
        orientation = "h",
        
        node = list(
          label = node_names,
          color = "grey",
          pad = 15,
          thinkness = 20,
          line = list(color = "grey", width = 0.5)),
 
         link = list(
           source = links$source,
           target = links$target,
           value = links$value))

plotly_IMAGE(p, out_file="out.png")

如果我删除最后一行代码 plotly_IMAGE(p, out_file="out.png")，则没有错误。

Answer 1

plotly_IMAGE 用于使用 plotly chart studio. You need an api_key for this to work. See this 或 help(signup, package = 'plotly').

将图形导出为静态图像

如果要在本地 PC 上导出静态图像，可以使用 plotly::save_image(p, "plot.png")。

为了 save_image 工作，请考虑以下事项：

kaleido() requires the kaleido python package to be usable via the reticulate package. Here is a recommended way to do the installation:

install.packages('reticulate') reticulate::install_miniconda() reticulate::conda_install('r-reticulate', 'python-kaleido') reticulate::conda_install('r-reticulate', 'plotly', channel = 'plotly') reticulate::use_miniconda('r-reticulate')

作为替代方案，您可以使用

htmlwidgets::saveWidget(partial_bundle(p), file = "plot.HTML", selfcontained = TRUE)

将您的图表保存为独立的 HTML 文件（例如，已完成）
