How to get multiple Correlation Coefficients
Hi I have used a polycor package for categorical correlation coefficients. I run the following script. But there were no results. Could you tell me how to correct the script? Thanks in advance, vars <- names(sdi) for (i in 1:length(vars)) { for (j in 1:length(vars)) { paste(vars[i]," and ", vars[j]) polychor(vars[i], vars[j]) # corr } } -- Kum-Hoe Hwang, Ph.D.Phone :

In 1990 the specialZone urban policy was introduced. I guess that the effects of this specialZone policy would be different from countys.

[msan] Failing mmap.cc test
The mmap.cc test is failing for me on aarch64 SuSE 12. The assert assert(AddrIsApp(p)) fails. The last value printed from mmap is 0xf00000000 which is indeed not MAP_FAILED but also not a valid address acoording to mmap.cc's mapping table. Is there something about SuSE 12's kernel that behaves differently from what this test expects? I am not a kernel guy... The sequence of the last

Plotting two 3-dimensional time series in a 3 x 2 plot - alternatives to par(mfrow())
I am trying to plot two 3-dimensional time series in one window (such that there will be 3 rows and 2 columns). For zoo and ts objects the par(mfrow...) option does not work. I can get xyplot to make the plots, but data are on widely different scales in the three dimensions, and xyplot uses the same scale on all y-axis which means that in some dimensions the curves will be almost horizontal lines.

Newbie question: Linear regression with error bars.
Hello guys, I am a total newbie on R, having downloaded it, read the documentation and started playing with it right now.
