[R] Simple Function doesn't work?

[baptiste auguie]

Hi,

The error message,

Error in grid[i] <- x + (i - 1) * (y - x)/m :
  object of type 'closure' is not subsettable

indicates that "grid" is actually known to R as a function (type grid
to see its definition). You can define your own variable with the same
name, but that needs to be done before the assignment in the for loop,


ReturnsGrid = function(x,y,m){

grid <- vector(length = m)

for (i in 1:m){
  grid[i] <- x + (i-1)*(y-x)/m
}
grid
}

ReturnsGrid(0,9,3)


HTH,
