here is the example
this is how i read my data
assign("oldfilename","d:\\documents\\wahl99\\nrw95testin.csv",envir=.GlobalEnv)
olddata<-read.csv(oldfilename,as.is=TRUE,sep=";",header=FALSE,
col.names=c("nr","name","wb95","abg95","glt95",
"sp95","vp95","fp95","gr95","lif95"))
when i then compute
olddata["sp95"]/olddata["wb95"]
r 1.3.1 is ok,
and r 1.4.0 says
Error in FUN(left, right) : non-numeric argument to binary operator
