Dear all, again me I have already updated my version of R. But still appears this message: plot(ctree(Surv(hours,state)~soil+volatile, data=data)) Error in loadNamespace(name) : there is no package called 'Formula' I cannot find a package "Formula" in my list of packages. What to do in that case?
As you were instructed yesterday: Simply install the package "Formula".
You can do this in R on the command line
install.packages("Formula")
or using the graphical user interface if you are using one...
Thank you, Xavier
