我使用的是RStudio版本0.98.484和R版本3.0.2（2013-09-25） - Mac OSX 10.6.8上的“飞盘航行”。
这是一个代码示例：
a <- "a"
b <- "b"
c <- "c"
d <- "d"
e <- "e"
f <- "f"
model1 <- ug(~a:b, ~a:c:d,~b:c,~a:c:d:f,~d:e:f,~b:f)
model1 <- as(model1, "igraph")
应用这些功能：
cluster.distribution() #or
degree.distribution()
返回错误：
Error in cluster.distribution() : could not find function "hist"
Error in degree.distribution() : could not find function "hist"
现在我发现了这个：
https://github.com/igraph/igraph/issues/257包含以下内容： https://github.com/igraph/igraph/commit/0567c2694a99686bbd1855299822ad52dcd5989a slution。
但问题似乎有所不同，因为它是在我的3.0.2 R版本下不能工作的hist（）函数而不是“$ intensityities”。
我从这里下载了最新版的igraph包： https://code.google.com/p/igraph/downloads/detail?name=igraph_nightly_0.7-f8164af-20131004.tar.gz&can=2&q=
然而，当我尝试使用以下方法在终端中安装它时： R CMD INSTALL~ / Downloads / igraph_0.7.tar.gz
