I am doing a survival ctree with party package (R software) and i would like to have coloured survival curves in the terminal panel.
fitform <- Surv(delai_efs ,evt_efs) ~ age + sexer + ... + bmiins + tailler +
tree = ctree(formula = fitform, data = taclfknn, controls = ctree_control(teststat = "max", testtype = "Teststatistic")
plot(tree)
I tried to change the source code integrating additional arguments like color or using gp = gpar(col=...)
but i failed...
Any help ?
Thanks
Here is the solution for function ctree
from partykit
package.
You can specify plotting parameters for different types of terminal nodes. All parameter for your case can be found ?node_surv
To change a colour of survival curve:
plot(tree, terminal_panel=node_surv(tree, col="green"))
