Dear all,

I am trying to adjust the DHS point (GPS) data using the R script, provided by "Guidelines on the use of DHS GPS data". But unable to create the buffer around GPS points.
I have used the code below,

pdsc <- disc(radius = offset.dist[i], centre = c(coordinates(pts)[i,1],
coordinates(pts)[i,2]))

I can't understand what would be the value of "i"?.....what is the meaning of "i" here?

Hi,

`i` refers to an entry in ` 1:nrow(pts)` which is being iterated through with a for loop

best,
