运行以下代码时
# Sample an adjacency matrix:
set.seed(1)
adj <- matrix(sample(0:1, 10^2, TRUE, prob = c(0.8, 0.2)), 10, 10)
# Run qgraph:
qgraph(adj, images = file, labels = FALSE, borders = FALSE)
## "**Error in cex + offset : non-numeric argument to binary operator**"
在运行上述示例代码时,我使用 R 3.0.0 得到上述引用错误,并且 qgraph 版本是最新版本,即 qgraph_1.2.2
I need help to work further
