Yes, I realized that I had forgotten to require(plotrix) after I sent

Jim,
thanks for the hint to diamondplot. It is much closer natively to what I
wanted to do, and

Thanks, Jim,
this one works (with your random data)! (In case anyone reads and wants
this as well, package plotrix provides radial.plot.)
The overlap is normal, because it's random data. When the respondents
have a less random streak of answering
First of all, I really like R! Still being a newbie, I find things (the
difficult ones) to be very simple.
Alas, some 'simple' things still escape me. (Maybe the tutorials are
often too much focused on the 'difficult' items??)

Hi:
The first part is straightforward. You didn't supply example data,
but it's easy to generate it oneself:
likmat - matrix(sample(1:5, 310, replace = TRUE), nrow = 31)
dim(likmat)
# [1] 31 10
frq - t(apply(likmat, 2, table)) # 10 x 5 matrix, questions in rows
As for the plot,

And, now somewhat less of the ordinary, a spider/radar showing the
number of responses for each question (circular axis, 10), with the
frequencies as radial axes. That is, 5 polygons showing the frequencies
of the responses per each question.

Hi Uwe,
Here's one way to get your spider plot:
ld1-matrix(sample(1:5,310,TRUE),nrow=31)
ld2-apply(ld1,2,table)
radial.plot(ld2,line.col=2:6,rp.type=p,
radial.pos=seq(0,9*pi/5,by=pi/5),
labels=paste(Q,1:10,sep=),start=pi/2,
