I tried that too, it doesn't work because of the way I wrote the code.
Listing y as free or not giving it a limit makes the scale go from -0.5 to
0.5, which is useless. This is what my code looks like now (it's S-Plus
code, btw)-- I'll try reading up on lattices in R to see if I can come up
with something better.
par(mfrow = c(2,2))
unique.id <- unique(d1$ID)
unique.id <- sort(unique.id)
for(j in unique.id){
temp.id <- d1[d1$ID==j,]
unique.dose <-unique(temp.id$DOSE)
plot(0,0,type="n",
xlab= "Time (hr)",ylab="Concentration (ug/L)",
xlim=c(0,32),ylim=c(0,200),
main=paste("ID",j)
)
for(i in unique.dose){
temp.subanddose <- temp.id[temp.id$DOSE==5,]
points(temp.subanddose$TAD,
temp.subanddose$DV,col=1,pch=1,)
points(temp.subanddose$TAD,
temp.subanddose$IPRE,type="l",col=1)}
for(i in unique.dose){
temp.subanddose <- temp.id[temp.id$DOSE==7,]
points(temp.subanddose$TAD,
temp.subanddose$DV,col=2,pch=2,)
points(temp.subanddose$TAD,
temp.subanddose$IPRE,type="l",col=2)}
for(i in unique.dose){
temp.subanddose <- temp.id[temp.id$DOSE==10,]
points(temp.subanddose$TAD,
temp.subanddose$DV,col=3,pch=3,)
points(temp.subanddose$TAD,
temp.subanddose$IPRE,type="l",col=3)}
key(text=list(c("5 mg", "7 mg", "10 mg")),lines=list(type=rep
("l",3),col=1:3),border=T,corner=c(1,1))
}
