wmap <- readOGR(dsn="~/R/funwithR/data/ne_110m_land", layer="ne_110m_land")
This code is not loading the shape file and error is generated as
Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, :
Cannot open file
I am sure that the directory is correct one. At the end / is also not there and layer name is also correct.
Inside the ne_110m_land directory files I have are:
ne_110m_land.dbf
ne_110m_land.prj
ne_110m_land.shp
ne_110m_land.shx
ne_110m_land.VERSION.txt
ne_110m_land.README.html
You could have shown that you have the right path with:
list.files('~/R/funwithR/data/ne_110m_land', pattern='\\.shp$')
file.exists('~/R/funwithR/data/ne_110m_land/ne_110m_land.shp')
perhaps try:
readOGR(dsn=path.expand("~/R/funwithR/data/ne_110m_land"), layer="ne_110m_land")
or a simpler alternative that is wrapped around that:
library(raster)
s <- shapefile("~/R/funwithR/data/ne_110m_land/ne_110m_land.shp")
