Hi,

I read some MapInfo TAB-files (or MID MIF, same result) like this:
shp_0 <- rgdal::readOGR(dsn=fnP, layer=xR)

When I look at summary(shp_0) I get:
-------------------------------------------
Is projected: FALSE
proj4string :
[+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs +towgs84=0,0,0]
-------------------------------------------

Note: "No units="!

The coordinates I read are lat long and show up correctly when I plot them
on maps. But the problem is I need to use the Area-info for each polygon,
and the values associated to each polygon are extremely low, like
0.000323445. The largest area-number I've ever seen is 0.04.. The polygons
should be in the tens or hundreds of square kilometers.

I suspect the readOGR is using another default-unit than meters. How can I
know what it is or how to set it, so that readOGR calculate areas I can use?

By the way, if I look in the Mapinfo-MIF file, it has "CoordSys Earth
Projection 1,104". Not sure if that is relevant here.

Have a great weekend everyone.

/Chris
