Here's another way with spbabel.
library(dplyr)
library(spbabel)
pts <-
tibble::tribble(~ID, ~x, ~y, ~grp,
1 , -33, -23,1,
2 , -32, -23,1,
3 , -32, -22,1,
4 , -33, -22,1,
5 , -32,
Hi Antonio,
have you tried with sf? Like:
library(sf)
pts <-
tibble::tribble(~ID, ~x, ~y, ~grp,
1 , -33, -23,1,
2 , -32, -23,1,
3 , -32, -22,1,
4 , -33, -22,1,
5 , -32, -23,2,
Thanks Lulla,
Nice solution. I could also export it as a shapefile after transforming it
to a spatial polygon dataframe.
The problem is that I could not "individualize" the squares in a multipart
layer. They all have the same ID. I tried to change this without success:
"Single ID required".
The
Maybe something like this?
poly <- SpatialPolygons(list(Polygons(tapply(seq_len(nrow(vertices)),
vertices$cod,
function(x)
Polygon(vertices[x,1:2])), ID="1")),
Hi,
I have a data.frame with the vertices (lon / lat) and codes from several
squares (more than 500 in the real dataset).
I want to create an object with these polygons (squares) and after this
export it as a shapefile.
With the script below I can draw one square.

Dear Ákos and Vijay,
Thank you very much for the solutions. They work perfectly!

And if you need coordinates as part of your data frame just do
cbind(coordinates(x), as.data.frame(x, xy = TRUE))

Dear Milu,
I think that you are looking for as.data.frame(x, xy = TRUE).
