[R] list inside a for loop

Hi All, Trying to figure out the way to create a vector of values inside a loop I have a matrix pop: Id yloc xloc weight 1 2 . and spatial grid grid.dens with "coordinates" (x=xloc,y=yloc) I want to create two more vectors: Food and Consumed inside the loop and add those to pop so: Id

[R] 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
