search for: pompt

In the latest version R2.7.0 the following command does not work anymore: x <- eval(parse(prompt = paste("give value for x > "))) It does give the pompt, but the object x is not created. We think this is due to a bug in the function parse. best regards, Wout Slob ____________________________________________________________________________ DISCLAIMER: http://www.rivm.nl/disclaimer.htm\ ...{{dro...{{dropped:3}}

Hi, I'm doing some easy calculations to normalize some values. This looks like this: x=mean(a+b+c+d ...) a=a-x b=b-x c=c-x d=d-x ... mean(a+b+c+d ...) ---> Should now be 0! However, I'm getting results like -2.315223e-18 This is really near to 0 but not very aesthetic. Can I prevent this? Or is this behaviour desired? Thank you very much!
