Question

我试图重现教程中的示例（第7页）

https://cran.r-project.org/web/packages/WeightedCluster/vignettes/WeightedCluster.pdf

开始之前

R> seqtreedisplay(wardTree, type="d", border=NA, showdepth=TRUE)

我需要安装GraphViz，但它不再在CRAN中，所以我从bioconductor安装它并且工作正常

source("https://bioconductor.org/biocLite.R")
biocLite("Rgraphviz")

我安装的库是库（Rgraphviz）它正确加载但在运行时 R＆GT; seqtreedisplay（wardTree，type =＆＃34; d＆＃34 ;, border = NA，showdepth = TRUE）

我收到错误

Error in disstreedisplayInternal(tree = tree, filename = filename, tmpdisstree = tmpdisstree,  : 
   [!] GraphViz was not found. If you haven't, please install GraphViz to use this function: see http://www.graphviz.org
 [!] If GraphViz is installed on your computer, you need to specify the GraphViz installation directory using the argument gvpath='installdir'
 [!] You can also add this directory to the PATH environment variable
 [!] GraphViz installation directory usually looks like 'C:\Program Files\GraphViz'
In addition: Warning message:

那个应该安装和加载的库吗？由于GraphViz之前的名称发生了变化，我感到很困惑，现在它似乎是Rgraphviz

Answer 1

TraMineR及其seqtreedisplay函数不使用Rgraphviz包。

要使用seqtreedisplay，您需要安装（R之外）独立的 GraphViz 程序，您可以从http://www.graphviz.org/下载该程序。

您可能需要在路径中添加该程序的路径。

由于GraphViz，错误seqtreedisplay
