data.frame operations
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:

sum data from data.frame in a matrix
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!...

return object from loop inside a function
...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$weight[i]*0.25)
Left=Food-Consumed
grid.dens[pop$yloc[i],pop$xloc[i]]=Left #update grid.dens values on i
pop$birth[i]=pop$birth[i]+1
}
return(pop)
return(grid.dens)
}
I get an updated pop, but not an updated grid.dens. What am I doing wrong?

overlaying a set of 'grouping' lines on a plot from image()
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
