hello R-Users, I have this simple but not for me question:
I do:
> res<-dbSendQuery(con, "SELECT * FROM tabellaProva") > myDataFrame<-fetch(res) > myDataMatrix<-as.matrix(myDataFrame[,-1]) > namerows(myDataMatrix)<-as.character(myDataFrame[,1])
and I have:
io tu io "0" "1" tu "1" "0"
my problem is that the content of the matrix is interpreted by R as strings, not as numbers.
Is there a way to convert those characters to numbers like
io tu io 0 1 tu 1 0
thanx in advance, simone
