Local_coord
Hello K?tia,
That sounds more like a dataframe manipulation problem; though we can
help. See the code below.
library(dplyr)
coord <- read.table('Coord_ha_R.txt', header = TRUE, fill = TRUE)
plots <- 'ref_sub_parc_coord.txt' %.%
read.table(header = TRUE) %.%
mutate(Sub_parc = seq(1,10)) %.%
merge(coord, by = 'Sub_parc') %.%
mutate(X_global = X_local + X, Y_global = Y_local + Y)
Is it more or less what you're aiming at? There are certainly many ways
to come to the same result.
Also you may want to take a look at the dplyr vignette, it's a quick
read.

Hi there, I need to consolidate my local coordinates gotten in 10x10m sub-plots and to transform them into 100x100m reference. I am doing this by hand in excel... too much time!! I need to sum up a reference measure to subplots measure by creating a loop.. The file "Coord_ha_R" has the columns names "ParcelaSub_parcX_localY_local" The reference file (ref_sub_parc_coord) to sum up values to X and Y_ local has the colums name "sub-parcXY". For each "XY_local fields in the "coord_ha_R", I need to sum up the respective XY values in the "ref_sub_parc_coord" file, considering each sub-parcel. I'll really apreciate any help, because I have too many plots!! Thanks -- K?tia Em?dio da Silva DSc Eng. Florestal Manaus/AM Forestry Engineer Manaus/AM-Brazil
