```Dear all,

I have following data called "paitent"

day    patient1    patient4    patient5    patient6
0   -0.27842688 -0.04080808 -0.41948398 -0.04508318
56  -0.22275425 -0.01767067 -0.30977249 -0.03168185
112 -0.08217659 -0.26209243 -0.29141451 -0.09876170
252  0.08044537 -0.26701769  0.05727087 -0.09663701

where each patient have response values at four time
points. I want to plot each patient's values over time
on the same plot where the value points are connected
by line. That is, the graph will have four lines for
the four patients. I tried the program below but
couldn't make it work correctly. I'm new beginner and
haven't yet learned how functions line and points work
together. Hope you can help me out.

par(mfrow=c(1,1))
plot(patient[,1],patient[,2], pch=1,
type="l",col=1,cex=1,lwd=2,
xlab="Days", ylab="Patient
response",cex.main =1,font.main= 1,
main=NULL)

points(patient[,1],patient[,3],col=2,pch=1,cex=1)
lines(patient[,1],patient[,3],col=2,lty=1,cex=1)

points(patient[,1],patient[,4],col=3,pch=1,cex=1)
lines(patient[,1],patient[,4],col=2,lty=2,cex=1)

points(patient[,1],patient[,5],col=4,pch=1,cex=1)
lines(patient[,1],patient[,5],col=2,lty=1,cex=1)
points(patient[,1],patient[,6],col=5,pch=1,cex=1)
lines(patient[,1],patient[,6],col=2,lty=1,cex=1)
