# S3 method for data.frame
sp(x, attr_tab = NULL, crs, ...)

Arguments

x: tibble as created by sptable
...: unused
attr_tab: remaining data from the attributes
crs: projection, defaults to NA_character_

Value

Spatial*

Examples

library(dplyr)
#> 
#> Attaching package: ‘dplyr’
#> The following objects are masked from ‘package:stats’:
#> 
#>     filter, lag
#> The following objects are masked from ‘package:base’:
#> 
#>     intersect, setdiff, setequal, union
semap1 <- semap  %>% dplyr::filter(y_ > -89.9999)
sp_obj <- sp(semap1, attr_tab = seatt, crs = "+proj=longlat +ellps=WGS84")
#> New names:
#> • `object_` -> `object_...1`
#> • `object_` -> `object_...7`
## look, seamless Antarctica!
## library(rgdal); plot(spTransform(sp_obj, "+proj=laea +lat_0=-70"))
