Dear all,
I have a function that for a variable number of inputs plots them to the same
plot
I am doing this quite simply by
plot(seq(from=start, to=stop, length.out=np),
datalist[[1]]$dataset
xlim=c(start, stop), ylim=c(0, 1),
type="l")
if (length(datalist) > 1)
{
for (i in 2:length(datalist))
{
np <-
length(datalist[[i]]$dataset)
lines(seq(from=start, to=stop, length.out=np),
datalist[[i]]$dataset$, lty=i)
}
}
as you can see, specifically this line
lines(seq(from=start, to=stop, length.out=np), datalist[[i]]$dataset$
lty=i)
is changing the line type so any different input is plotted with different line
type.
This works quite well for 6 lines but if the arguments are more than 6 (in my
case 7) the line type starts from the beginning. Is it possible to keep that
loop and have the lines produced in plots a bit more customized (like lines with
squares and or cubes).
I have already checked in the ?par
but I can not find how I can modify the line in that sense, and especially doing
this smart inside a for loop.
Could you please help me with that?
I would like to thank you in advance for your help
Regards
Alex

What do you want to change about the lines? pch (different characters) might give the desired variety.

Hi If you want to have more than 6 line types you had either to use colours or to follow last part of lty advice from par and go to section "Line types". In that case you can not sim?ply use lty 1,2,...,n but you have to prespecify line types in some character vector and choose from that vector. Quote Line types can either be specified by giving an index into a small built-in table of line types (1 = solid, 2 = dashed, etc, see lty above) or directly as the lengths of on/off stretches of line. This is done with a string of an even number (up to eight) of characters, namely non-zero (hexadecimal) digits which give the lengths in consecutive positions in the string. For example, the string "33" specifies three units on followed by three off and "3313" specifies three units on followed by three off followed by one on and finally three off. The ?units? here are (on most devices) proportional to lwd, and with lwd = 1 are in pixels or points or 1/96 inch. However with more than 6 lines in one colour the picture will probably resemble mad spider net.

Here is one with the default five broken lines and five more that are reasonably distinguishable: mylinetypes=c("44", "13", "1343", "73", "2262","7272","5331","3366","2714","6224") plot(1:10,type="n") for(i in 1:10) abline(h=i,lty=mylinetypes[i]) Work out a way to generate different line types automatically? You might be able to do this by some tricky algorithm that applied a sequence like (+3,-2,+1,-1) to your index and then rotating the sequence on each iteration, BUT, your plot would still probably look like a mess with more than ten lines.
