[STATSGRASS] sites.put2 ERROR!!!

[Massimiliano Cannata]

Hi users,
I'm new of this list and I will appreciate any
help.
Here it is what I've done:

>library(GRASS);
>G<-gmeta();
>mod<-lm(.....................)
>dataSite<-data.frame(x=matrix(1:11),y=matrix(1:11),z=as.vector(mod$coefficient));

>sites.put2(G,data=dataSite,id=NULL,dims=c("x","y","z"),lname="parametri",all.sites=TRUE,check=FALSE)

Error in
which(unlist(lapply(data.attr,is.numeric))):
    argument to "which" is not logical
>

But if I type:

>lapply(unlist(dataS,is.numeric))
    x        y        z
TRUE    TRUE    TRUE

So, what I'm doing wrong?
Of course I can use sites.put() but just for
knowledge.......

Thanks you all.
