Hi Dennis, Thanks for your quick response and sorry for not being clear. That helped, but I need an actual matrix of e.g., 12 x 12 and those functions give me a matrix with only the "filled" locations. I need a 12 by 12 matrix with sums (0 if there's not data and the actual sum where there is) as follows: 1 2 3 4 5 6 7 8 9 10 11 12 1 0 0 0 . . . . . . 0 0 0 2 0 0 0 . 3 0

Hi All, I've been doing circles with this all morning, although I'm sure there's a simple solution. I have a data.frame "pop" as follows: > pop ind xloc yloc gonad 1 1 5 2 12 2 1 5 4 25 3 1 3 3 30 4 1 5 4 10 5 1 1 4 08 . . . . . 10 1 1 4 11 And I need the following steps: 1. Sum

Hi all (again), I have a data frame "pop": xloc yloc yield 1 10 12 95 2 11 10 81 3 12 11 20 4 12 11 10 And I want to get the sum of yield for the cell (pop$xloc, pop$yloc) in a matrix as follows: xloc 10 11 12 10 0 81 0 yloc 11 0 0 30 12 95 0 0 Any ideas? thanks! Nico

Hi All, I'm trying to delete a row from my dataframe "pop" without changing the indexing (column 0) as follows: >pop id birth size xloc yloc weight energy gonad consumed 1 1 36 13 34 43 0 18 0 0 2 2 36 10 39 38 0 18 0 0 3 3 36 10 37 35 0 18 0 0 4 4 36 10 31 25 0

I think I found a bug in the Cairo library, plus weird behavior in both the Cairo and the normal pdf device. The baseline of the spades symbol seems to be off. This is easier to show than it is to explain. The problem does not appear in the normal pdf device, which is why I am guessing this is a Cairo bug. moreover, I cannot figure out why three of the card symbols seem to be transparent, but

Hi! I have 2 data.frames: "fish" and "popn": >fish xloc yloc id birth size weight energy gonad 20 15 15 54 -60 107.9 63.0 15952.9 8.0 21 15 15 32 -60 105.1 61.4 15538.8 7.8 91 4 43 96 -60 118.9 69.4 17573.2 8.8 71 32 4 64 -60 121.6 71.0 17976.0 9.0 34 2 64 20 -60 116.2 67.9 17173.0 8.6 95 6 20 58 -60 106.5

Hi, How does one change the dot for the median in a boxplot drawn using lattice? I have been looking at > names(trellis.par.get()) [1] "grid.pars" "fontsize" "background" [4] "panel.background" "clip" "add.line" [7] "add.text" "plot.polygon"

Hi All, I have a for loop inside the function and I cannot get UUU to give me an updated grid.dens object when I run the function (it does update when I run just the for loop). Here's a simplified version of my function: UUU=function(pop, grid.dens) { for (i in 1:10){ Food=grid.dens[pop$yloc[i],pop$xloc[i]] #use initial grid.dens values Consumed=(pop$weight[i]*0.25) Left=Food-Consumed

Hi All, I?m trying to superimpose (or "add") two matrices: 1. resulting from a table function with frequencies: > U=table(pop$xloc, pop$yloc)) 14 15 16 17 18 19 20 21 22 5 0 0 0 0 0 0 0 0 0 7 0 0 0 0 0 0 0 0 0 8 0 0 0 0 0 0 0 0 0 9 0 0 0 0 0 0 9 0 5 10 0 0 0 0 0 0 0 0 0 11 0 0 0 0 0 0 0 0 0 2.

Hello, I am drawing a boxplot using bwplot in lattice. I would like to learn how to draw a thicker median line instead of the default setting. Thank you. Code bwplot(........, pch=rep("|",2)) Elaine [[alternative HTML version deleted]]
