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

Hello, I'm trying to create a matrix (95x55) with data from a data.frame pop: xloc yloc go ind Ene totW 1 23 20 516 1 0.02 20.21 2 23 20 1143 1 0.02 20.21 3 23 20 250 1 0.02 20.21 4 22 15 251 1 0.02 18.69 5 22 15 598 1 0.02 18.69 6 21 19 250 1 0.02 20.21 7 22 20 251 1

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 (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

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]]

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, I have a matrix that I am displaying via image. I would like to obtain an image where the columns are 'grouped' (I have a grouping variable). But I am not sure how how I can draw the lines to indicate the grouping in the margin. I realize this is essentially waht heatmap does but as I have a set of custom breaks and colors I wanted to generate this via image. I can see that it is a

Hi all, I was trying to test ROUTE specific code with a multi-isp serviced box. There is a bug somewhere, but I''m not able to understand what the real problem is: when I issue a "shorewall show capabilities" I get: Loading /usr/share/shorewall/functions... Processing /etc/shorewall/params ... Processing /etc/shorewall/shorewall.conf... Loading Modules... Shorewall has
