Hi Dear R users, For a pair plotting, usaully we use par( ) function. Apparently it does not work anywhere. I want to have 3 plots in a single figure, like this: par(mfrow=c(3,1)) densityplot( a) densityplot(b) densityplot(c) But it does not work. How is it possible to have such a figure with densityplot( ) in a single figure? So many thanks for any help. Amir Safari

Dear R users, I hope this mailing list be the right place for my question. Usaully performance criterion of curve fitting like as Directinal Symmetry (DS) and Mean Absolute Percentage Error (MAPE) are correctly used with absolute time series which includes only positive values. But how it is possible to use DS and MAPE with other time series like as return series (for example return of a

Dear R Users , As a beginner in QP, I'm trying to solve a Support Vector Machine problem by a QP. In particulare I am using the quadprog package. My questions are here: 1- In the document for the package (The quadprog Package), the inequality constraint is mentioned with >= , however in a standard QP, this usaully is written with <= . This constraint should be multiplied by a

I'm posting this for two reasons: one is to see if anyone has a better way of solving the problem or suggestions for improving my existing approach; and the other is to show what I'm currently doing in case anyone else might find it useful. The background is that I've been using Sweave for several years now to produce class notes, and I sometimes include quite a lot of raw R input and

A friend of mine came to me with the two envelopes problem, I hadn't heard of this problem before and it goes like this: someone puts an amount `x' in an envelope and an amount `2x' in another. You choose one envelope randomly, you open it, and there are inside, say ?10. Now, should you keep the ?10 or swap envelopes and keep whatever is inside the other envelope? I told my friend

I finally found it, thanks to a clue from https://wiki.archlinux.org/index.php/Active_Directory_Integration This works: kinit -k -t /etc/krb5.keytab 'WRN-RADTEST$' These don't work: kinit -k -t /etc/krb5.keytab kinit -k -t /etc/krb5.keytab host/wrn-radtest.ad.example.net kinit -k -t /etc/krb5.keytab host/wrn-radtest That is: the keytab contains three different principals: root
