RE: [R] multiple peaks in data frame
I don't quite understand your English, but I'll take a stab at answering your question. If by date you mean data and by peaks maxima, then df - data.frame(V1=c(23, 4, 56, 7, 99, 33)) interval - 2 if (nrow(df) %% interval == 0) tapply(df$V1, rep(1:(nrow(df) / interval), each=interval), max) might be what you need.

For example if dates are: 1 23 2 4 3 56 4 7 5 99 6 33 extract the date i wanted to divide into intervals of 2 an d to take alone the numbers 23, 56 and 99 of those 3 intervals.

[R] axis annotation
Hi, Is there a way to specify a vector of colors for the tick annotation in a call to axis(), to achieve the x-axis here?

Doh! The second loop should be for (j in i:min(i+3, 16)) { Thanks for the help!

But when I comment X11(), and uncomment the first and last lines, the postscript file I get has 10 pages! You do have 40 plots so you should get 10 pages with 4 plots on each page. However, X11() is only called 4 times that is why you only have four plot windows popping up. Pages plotted on the same plot window will override previous pages, for obvious reasons.

[R] legend
I think I'm missing something tonight in the usage of 'legend': plot(0, type=n) legend(locator(1), month.abb[1:5], pch=15, col=1:5) gives me something similar to what I want. But legend(locator(1), month.abb[1:5], fill=T, col=1:5) gives me 5 black boxes. What am I doing wrong?

[R] png()/jpeg()
When I execute the following code, it works just like I want it to: three pages of nine (or fewer) plots. However, when I execute the code with the first and last lines uncommented, I get three pages (files), but the 2nd 3rd pages have overlapping plots. It's like a new page wasn't created. I'm pretty sure I've either misplaced or left out a crucial call to some function, but I'm not sure where.
