[R-sig-Geo] +AFs-R-sig-Geo+AF0- +-AFs-R-sig-Geo+-AF0- Represent data on map

I could not work with the information by separately. I modified +ACI-manually+ACI- the +ACo-.dbf file associated to the +ACo-.shp file. I just pasted the columns with the information in the +ACo-.dbf file because I couldn't do it with R.

After that, I did:

library(sp)
library(maptools)
map +ADw-- readShapeSpatial(+ACI-ESTADOS+ACI-)
library(lattice)
trellis.par.set(sp.theme())
spplot(map, c(+ACI-A2010+ACI-, +ACI-A2013+ACI-, +ACI-A2000+ACI-, +ACI-A2005+ACI-), names.attr +AD0- c(+ACI-2010+ACI-, +ACI-2013+ACI-, +ACI-2000+ACI-, +ACI-2005+ACI-),
main +AD0- +ACI-Desempleo por estados en M+AOk-xico, 2000-2013+ACI-)

And this is the result: https://skydrive.live.com/redir?resid+AD0-C319779BEF3A0241+ACE-1539+ACY-authkey+AD0AIQ-AMe4-a2kRUFmAyM+ACY-v+AD0-3+ACY-ithint+AD0-photo+ACU-2c.png

Now, my trouble is the scale, that is in integer numbers, how do I can set the scale with decimals and the halves values (like 1.5, 2.5, 3.5.....)?.

I tried with:

spplot(map, c(+ACI-A2010+ACI-, +ACI-A2013+ACI-, +ACI-A2000+ACI-, +ACI-A2005+ACI-), names.attr +AD0- c(+ACI-2010+ACI-, +ACI-2013+ACI-, +ACI-2000+ACI-, +ACI-2005+ACI-),
main +AD0- +ACI-Desempleo por estados en M+AOk-xico, 2000-2013+ACI-, scale +AD0- 0.5, which +AD0- 2)

...and didn't work.

I hope you can help me.

Regards,

Rol+AH4-

no, because X2000 will be sought in object 'map'. In case 'map' and 'unem' have exactly identical geometries (polygons?), and these geometries occur in the same order, then

map+ACQ-X2000 +AD0- unem+ACQ-X2000

may suffice. If not, you might need to do a spatial match, e.g. by

library(sp)
data(meuse)
coordinates(meuse) +AD0- +AH4-x+-y
data(meuse.grid)
coordinates(meuse.grid) +AD0- +AH4-x+-y
gridded(meuse.grid) +AD0- TRUE

try(meuse+ACQ-dist +ADw-- meuse.grid+ACQ-dist) +ACM- fails, as geometries don't match

meuse+ACQ-dist +AD0- over(meuse, meuse.grid)+ACQ-dist +ACM- uses a spatial match

but still, if unem and map are both polygon geometries this may lead to errors, as over() finds (first) intersecting polygons, and neighbouring polygons touch each other, so intersect too.


+AD4- Is it a problema having separate shapefile information of statistic?, because there are two files, the .shp and csv, although these have the same identificator. I mean, the +ACI-CVE+AF8-EDO+ACI- +AD0- +ACI-num+AF8-est+ACI- and +ACI-NOMBRE+AF8-EDO+ACI- +AD0- +ACI-est+ACI- are the same value. I'm thinking if I have to paste the csv columns to the map object.

+AD4- Cannot help much without more information, but try:
+AD4- 
+AD4-   names(map)
+AD4- 
+AD4- Then pick one of the column names. Apparently, +ACI-2000+ACI- is not the name of a column of data in the map object.
+AD4- If map is like unem, then perhaps
+AD4- 
+AD4-   spplot(map, 'X2000')
+AD4- 
+AD4- is what you need.
+AD4- 
+AD4- Note, the c() in
+AD4-   c(+ACI-2000+ACI-)
+AD4- is not necessary. Simply
+AD4-   +ACI-2000+ACI-
+AD4- would be sufficient.
+AD4- 
+AD4- I am not familiar with the readShapeSpatial function+ADs- I always use
+AD4- readOGR() from the sp package.
