[R] Average curve in R

[Rui Barradas]

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

> 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.
