[R] Plotting Data Frame

[Petr Pikal]

Hi

That is default behaviour, see the help page

pch - character string or vector of 1-characters or integers for 
plotting characters, see points. The first character is the plotting-
character for the first plot, the second for the second, etc. The 
default is the digits (1 through 9, 0) then the letters.  

Use other options e.g. type, lty, pch if you want to modify 
appearance of the matplot output. Or use matlines.

It seems to me that you are messing ts.plots and matplots. It is 
always good to follow posting guide and give a small, 
**reproducible** example which depicts what you did and explain how 
your atempts failed. Without your data it is hard to decide what you 
want and how you shall do it.

Seems to me that
plot(...., ylim=....)
for (i in 6:18) {
lines(time, data[,i])
}
could be what you want but it is only a guess.
