[GRASS-stats] spgrass problem importing category 999 when plugin is FALSE

[Jarek Jasiewicz]

Hi

I during batch processing of couple of maps I found strange behaviour of 
readRAST6 when I import cell map with value 999.
Instead of 999 Na is imported (?? _

It is for me completely strange, so I test it with folowing:

echo "test_map=999"|r.mapclac
R
library(spgrass6)
testNoPlugin=readRAST6("test_map",plugin=FALSE)

summary(testNoPlugin at data)

     test      Min.   :    NA 1st Qu.:    NA Median :    NA Mean   :   
NaN 3rd Qu.:    NA Max.   :    NA NA's   :156740

testPlugin=readRAST6("test_map",plugin=TRUE)

summary(testPlugin at data)

     test   Min.   :999 1st Qu.:999 Median :999 Mean   :999 3rd Qu.:999 
Max.   :999 


It is very strange for me but I tested it on several maps. I think 
someone could try to reproduce this.
