Hello All,
I am using library party and I have found a curious/strange behaviour when
trying to save the output of a ctree in a file via jpeg/png command.
If you use:
library(party)
airq - subset(airquality, !is.na(Ozone))
airct - ctree(Ozone ~ ., data = airq)
plot(airct, terminal_panel = node_boxplot, drop_terminal = FALSE)
###
you get a perfect and nice graph, but when you try the equivalent but trying
to put the output in a file:
#
library(party)
airq - subset(airquality, !is.na(Ozone))
airct - ctree(Ozone ~ ., data = airq)
jpeg(filename = Rplot%03d.jpg, width = 1400, height = 800,
pointsize = 12, quality = 75, bg = white, res = NA)
plot(airct, terminal_panel = node_boxplot, drop_terminal = FALSE)
dev.off()
you will see that the boxplots at the terminal nodes do not appear...
On the other hand, when you try a similar approach with
##
plot(airct, terminal_panel = node_boxplot, drop_terminal = FALSE)
savePlot(file=paste(directorio,PartyTree,sep=),type=jpeg, device=
dev.cur())
dev.off()
#
you get everything perfectly fine, although with a lower resolution.
I am using the latest version available of your library (0.8-1) in a Windows
box.
Do you know if this is the expected behaviour or there is something abnormal
?

I checked this problem directly with the package creators/maintainers and
they recommended to post it here.
They have also provided very kindly a workaround while it is finally
corrected.
Thanks,
