I am trying to load several gpkg files into R but got some problems.
Initially this code works:
library("dplyr")
library("rgdal")
library("sp")
library("st")
library("sf")
setwd("C:\Users\filename.gpkg")
temp = list.files(pattern=".gpkg")
myfiles = lapply(temp, st_read)
Also, this works for each file (but I have more than 15 files):
st_read("filename.gpkg", layer= 'layerx')
But I need to specify the layer, so I code this way:
temp = list.files(pattern=".gpkg", full.names= TRUE)
tem2 = lapply(temp, st_read(dsn= '.',layer= 'layerx'))
But does not work, produce this error:
Error: Cannot open "C:\Users\"; The source could be corrupt or not supported. See `st_drivers()` for a list of supported formats.
Any ideas on how to solve this?
