Recently, I started using R Revolution, and I tried to run a example code to visualize a decision tree.
I ran the code:
data("kyphosis", package="rpart")
kyphTree <- rxDTree(Kyphosis ~ Age + Start + Number, data = kyphosis, cp=0.01)
library(RevoTreeView)
plot(createTreeView(kyphTree))
And got the error:
Error in tools:::httpdPort > 0L :
comparison (6) is possible only for atomic and list types
I searched about this error, I'm using the R 3.2.2 and already updated my Rstudio.
Someone could help me?
Tks,
Your problem is not related to RStudio. It appears to be a bug in the plot function for revoTreeView
. The error shows that a comparison is being made with tools:::httpdPort
(first few lines of the plot.revoTreeView
function). This is a function, not a number. Please submit through your Microsoft support channels.
