Dear List,
I have an array of 6400 x 56 elements. I want to calculate the density function for each column and plot all 56 density functions in one plot.
I have tried several procedures, but they all failed.
What can I do?
56 lines could even confuse a spider, so you might want to re-think your plotting approach. However....
## untested code! ## get a density object for each column. den.list <- apply(zz,2,density)
## set up your plot window
all.x <- sapply(den.list,function(d,...) {d$x})
all.y <- sapply(den.list,function(d,...) {d$y})
plot(all.x,all.y,type="n")## now plot each one on that graph ## this will make each line the same colour; for ## different line types or colours, you'll probably ## have to use a for() loop.
lapply(den.list,function(d,...) {lines(d$x,d$y)})
There's probably a much, much cleaner way to do that, though. I think the sm library has the sm.density function that takes an "add" argument to its plots... too busy to check that out on this box, however.
Cheers
Jason
