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:

And I need the following steps:

Fwd: Re: sum data from data.frame in a matrix
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 .

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
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

Symbol Font Baseline, Cairo, Card Symbols
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

EXTRAER MES EN LETRAS Y CASTELLANO
Buenas tardes,
Estoy precisando generar una nueva variable que contenga el mes en tres
letras, por ejemplo: ENE , FEB, MAR , ABR y así sucesivamente a partir de
los valores que ahora tengo en el Dataset, que son 1, 2, 3, 4 y así
sucesivamente.
Entiendo que sería con mutate, pero consulto acerca del comando completo..
Gracias,
Jesús

filled.contour and NA's
Hi,
I'm trying to do a filled.contour plot where some points are labelled as
NA. How do I could plot this kind of graphics, so NA points are coloured
black, keeping the levels of remaining points. NA's values represent
land points (meaningless), and what I want to plot is the levels of a
variable over the sea.
