Hello,
Just to add a note, since R defaults the x axis to the integer sequence
1:length(what.to.plot), this would do it:
plot(rowMeans(datQ), type="l")
If the op wants to plot this mean values line together with the other 4,
one of the most forgotten plot instructions is the matrix plot instruction.
matplot(datQ, type="l", col=2:5)
lines(rowMeans(datQ), col="black")
Hope this helps,
Rui Barradas

Hi Qamar,
I guess you are looking for row means vs. days plot.
If that is the case, try this:
datQ<-cbind(c(6,5,6,7,4,3,5),c(2,4,35,32,4,6,6),c(2,4,2,3,423,4,5),c(2,3,13,5,3,5,3))
datQmean<- apply(datQ,1,mean)
[1] 3.00 4.00 14.00 11.75 108.50 4.50 4.75
datQmean<-data.frame(datQmean)
days<-c(1:7)
datQplot<-data.frame(datQmean,days)
plot(datQmean~days,data=datQplot,type="l")
A.K.

Subject: [R] Average curve in R
Dear R users,
l
I have weekly data in the following manner
[,1] [,2] [,3] [,4]
6 2 2 2
5 4 4 3
6 35 2 13
7 32 3 5
4 4 423 3
3 6 4 5
5 6 5 3
I drew curve of each column against days (1,2,3,4,5,6,7). Now I want to draw an
average curve (a representative curve) of the whole data. Is there a way in R
to perform such operation? please reply ASAP as i have an assignment to submit
on monday.
Thanks in Advance..
regards
