在 R 中的矩阵的 x、y 坐标处分配向量

Question

I am moving from MATLAB to R and have a question regarding how to assign a vector at x , y coordinates of a matrix. For this, I tried with defining an array and then reading each pixel. I am stuck with reassigning values to the matrix after processing it. Following is my code:

GR_anom<-array(NaN,dim=c(180,360,100))
for (i in 1:180)) {
  for (j in 1:360) {
    GR_vec<-as.data.frame(GR[i,j,,drop=TRUE])
    Nonses= seasonaltrend(GR_vec,2002,2017)
    GR_anom[i,j,] <- Nonses[1]
  }
}

The line(GR_anom[i,j,] <- Nonses[1]) is written in the MATLAB format but in R it seems to work differently. I am stuck here since long in it, can you please suggest?

Answer 1

I have resolved the problem. The issue was the variable 'Nonses' is a list and therefore cannot be assigned to an array. In matlab everything is a matrix, so didn't think in that direction. Thank you very much for your responses.
