persp()
...n google and reading many pages I arrived to the conclusion that persp() could be used to draw that map.
I have prepared three small example files, which are supposed to be the files required for running that function.
xvector is a vector with the longitudes
yvector is a vector with the latitudes
zmatrix is supposed to the height, but since I only need a flat map I just gave the value 1 to each of the entries of the matrix (I am not sure this is correct though).
The first question for me when using persp() is that x and y values should be in increasing values (following the instructions), but I un...

zero-offset matrices
Has anyone written subscripting methods for matrices which are indexed
from zero? i.e. functions such as "[.zoffset" and "[<-.zoffset" which
would allow, given an appropriate function "zmatrix"
"zmatrix" <- function(...)
{
robj <- matrix(...)
class(robj) <- "zoffset"
robj
}
fred <- zmatrix(1:20, 4, 5)
fred[0, 4] # would be 17
fred[3, ] <- NA # would set the last row to NA
Many thanks, Jonathan.

Using "mean" if two values are identical
...PUT <- t( sapply( strsplit(INPUT, split=" "), as.numeric ) )
colnames(INPUT) <- c("x", "y", "z" )
# HERE START's my PROBLEM #
if (duplicated(INPUT[,1] & INPUT[,2] ))
zMEAN <- mean(INPUT[,3] )
# MATRIX with the mean-z values #
zMATRIX <- matrix(c(INPUT[,1], INPUT[,2], INPUT[,3] ), ncol=3, byrow=FALSE)

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi Stepan,
Sorry for the delay. It's great that you are working on MergeFunctions
as well and I agree, we should definitely try to combine our efforts to
improve MergeFunctions.
Just to give you some context, the pass (with the similar function
merging patch) is already being used in a production setting. From my
point of view, it would be better if we focus on improving its
capability
