Hi all-
So sorry to bother you all with something pretty basic.
I am trying to add the lines method output from svysmooth to a svyplot with
style="grayhex". However, the line either appears in the wrong place or if I
am running in R Studio it causes the system to crash.
I know this is something to do with Lattice graphics, but for the life of me I
can not figure out how. Dr. Lumley in his excellent book on page 118 mentions
that there is code on his website to do this, but I can not find it.
So for example:
library(survey)
data(api)
dclus2<-svydesign(id=~dnum+snum, fpc=~fpc1+fpc2, data=apiclus2)
svyplot(api00~api99, dclus2)
s1 <-svysmooth(api00~api99, dclus2)
lines(s1)
#works
svyplot(api00~api99, dclus2, style="grayhex")
lines(s1)
#does not work (line either appears in the wrong position in RGui or crashes
RStudio).
