[Rd] question

[Erich Neuwirth]

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
