Hi,
I have this plotting problem in lattice and appreciate any comments.
Say, I want to plot observed drug concentrations in point and prediction in
line
xyplot(CONC~TIME,data=df1,
panel=function(x,y,...){
panel.xyplot(x,y,type='p',col='blue')
PRED=df1$PRED
panel.xyplot(x,PRED,type='l',col='red',lwd=2)
}
)
This is working fine. Now I want to make the plot conditional on some
variable "TRT". It didn't work. I guess this is because the two panel.xyplot
functions have different "y", CONC and PRED. Only CONC is conditional on
TRT but not PRED. df1 is a data frame with elements TIME, CONC, PRED,....
Appreciate any comments.
xyplot(CONC~TIME|*TRT*,data=df1,
panel=function(x,y,...){
panel.xyplot(x,y,type='p',col='blue')
PRED=df1$PRED
panel.xyplot(x,PRED,type='l',col='red',lwd=2)
}
)
