similar to: substract 2 data.frames

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, 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

Dear all, I'm trying to perform a principal components analysis of a sample of individuals, and to plot it in 3D, assigning different colors according to the population each individual belongs to. Given that the matrix I have to use for the PCA cannot contain cualitative variables (here, the population of origin), I have no idea how can I do this in R. ANy help? Thanks in advance

Hello. I am new to R. And, I want to perform a multiple nested anova on a large datasets (with 9448 observations). Under the helps from R-Sig-ecology mailing list, I have gained many progresses. But I still have some confusions. I want to ask for some helps here. my dataset("SeedL.txt") was not attached. Data are not sorted by factors. In this dataset, "SpecN"

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

I am running 1.3.1 on a Windows (NT 4.0) machine. I've fit a nonlinear model intended to predict crop yield from nutrient information, and want to use the profile function. If I type say, profile(simparj.fm) I get the following error message: "Error in prof$getProfile(): number of iterations exceeded maximum of 5.25515e-308" I used the profiler function to profile simparj,fm step

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.

Hi all, Consider this ARM assembly code of a C function: 00008124 <foo>: 8124: push {r4, r6, r7, lr} 8126: add r7, sp, #8 8128: mov r4, r0 812a: ldrsb.w r0, [r2] 812e: cmp r0, #1 8130: itt lt 8132: movlt r0, #85 ;

As Adrian said, we'd need to see the source of foo() to assess what the location-list for bar ought to be. Without actually going to look, I would guess that 'poplt' is considered a conditional move, therefore r4's contents are not guaranteed after it executes (i.e. it is a clobber). If one operand of 'poplt' is 'pc' then of course it is also a conditional indirect

Hi, there I am a graduate student new to coding in S who is hitting a bit of a wall at present using an "optim" function. I am running into some troubles, and was hoping someone might be able to recognize where I am going wrong. As background: I have constructed a loop that carries out a 365-day calculation for a mass-balance model. Basically, the model depends on 2 variables (p,

Thank you all for taking a look at this. I pasted the C source then deleted it because I was afraid that it was too long to read... Here's the code of *foo*. Its real name is *verifyPIN*. The variable *bar* is *userPin*. int *verifyPIN*(char **userPin*, char *cardPin, int *cpt) { int i; int status; int diff; if (*cpt > 0) { status = 0x55; diff = 0x55; for (i = 0; i
