我正在研究矩阵、特征矩阵和网络图的数据可视化，并且我正在尝试通过网络图可视化一维心电图信号。我感觉现在的工具ggnet2可能plotly还不够，但我还没有完成基本测试，plotly因为我无法安装它。我经历了 3 次不成功的安装尝试阴谋地作为 R 提示符下的 root install.packages(plotly)，但我不断收到

答案1
httr取决于开放式SSL和卷曲包裹。该openssl软件包需要作为系统要求libssl-dev
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because openssl was not found. Try installing:
* deb: libssl-dev (Debian, Ubuntu, etc)
...
该curl软件包需要作为系统要求libcurl4-openssl-dev：
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libcurl was not found. Try installing:
* deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
...
因此，要安装，您需要运行：
sudo apt-get install libssl-dev libcurl4-openssl-dev
之后install.packages("plotly")应该可以工作。
