我有一个带有3个变量的df,“从”-“到”-“频率”。 “ from”具有5个级别,“ to”具有22个级别。“ Frequency”表示在原始DF中发生from-to连接的次数。
当我用此信息绘制网络时,该图仅显示“ from”中的5个节点,箭头指向空白。
为什么我不能绘制所有节点,包括“到”节点?
这是ggplot
的脚本:
ggplot(data=NetY, aes(from_id = from, to_id = to, linewidth =freq)) +
geom_net(labelon=TRUE, directed = TRUE, col = "darkred",vjust=-1, arrowsize = 1,
selfloops = TRUE, size = 15,arrowgap = 0.05,ecolour = "grey40", repel = TRUE,
labelgeom = "text", labelcolour = "black") + theme_net()
head(NetY)
from to Freq
